The LENA Pro and the LENA Research Language Environm= ent Analysis Systems are specifically designed for pediatricians, speech langua= ge pathologists (LENA Pro) and researchers (LENA Research). Both versions allow you to easily collect, process, and analyze language environment data for children 2 to 48 months of age. The system use= s highly technological LENA Digital Language Processors (DLP’s) and an advanced software package. The LENA Pr= o and LENA Research versions contain a client management feature that allows the = user to collect and manage multiple recordings from multiple clients or groups.<= span style=3D'mso-spacerun:yes'> The PC-compatible LENA Software can process 30 to 120 sixteen-hour recording files per month. Reports can be viewed in monthly, = daily, hourly, or 5 minute resolution time intervals. Audio files may be listened to and viewed. The software allows y= ou to mark, organize, and find specific audio segments; note-taking features allo= w you to attach research or clinician notes and comments to any report or specific audio segments. All data and = audio files are easily exportable to Excel. In addition, the LENA Research version provides access to the Infotu= re Time Segmented (ITS) file, which is a compilation of all algorithmic analys= es of the original audio file. The LENA Research version also has the capabili= ties to export TRS and CHA files.

About LENA and Infoture

Infoture, Inc. was founded in Boulder, CO in 2004, w= ith the goal to develop the LENA System, the world’s first automatic spee= ch monitoring and analysis system for infants and toddlers.

The LENA System is a revolutionary tool that was des= igned to remove the labor intensive difficulties of collecting and analyzing child speech data. You can also manage your clients and/or research participants = more efficiently with the LENA Client Manager feature. Infoture’s world-class team = of engineers, research scientists, linguists, and speech-language professionals has spent four years and millions of dollars researching and developing LENA. This research team gath= ered the world’s largest and most comprehensive database of spontaneous parent-child talk recorded in the natural home environment, resulting in ov= er 20,000 hours of speech data.

LENA Accurately and Reliably Measures the Natural Language Environment

The highly technological LENA System Digital Language Processor (DLP) reliably collects data in the natural home environment; the refined software package analyzes the data and provides percentile rank comparisons through a validated developmental snapshot as well as quantifia= ble speech language environment data.

The LENA DLP captures every utterance between a pare= nt, or other caregiver, and the child. The LENA Language Environment Software, which is based upon cutting-edge algorithmic-based speech recognition technology, uses advanced speech model= ing techniques to analyze conversations and noise within the natural home environment. Reports generate= d from the analyses present the number of Adult Words the child hears on the month= ly, daily, hourly, and 5 minute time resolutions. The reports also provide the numbe= r of Child Vocalizations (sounds or words uttered by the child) and Conversation= al Turns (parent-child interactions) that occur within the same time resolution scal= es. The LENA Developmental Snapshot is an age-appropriate questionnaire that provides an estimated developmental age compared with a child’s chronological age up to 48 months. This resource was designed by Infoture scientists and Speech Language Pathologists, and has been tested and validated.

For further information on the reliability and accur= acy of algorithmic-based segmentation, Adult Word count estimates, Child Vocalizat= ion classifications, and the Developmental Snapshot please refer to www.infoture.org/research.as= px to view Infoture Technical Report (ITR) 5, titled “Reliability of the LENA™ Language Environment Analysis System in Young Children’s Natur= al Home Environment.”

DLP Modes

Charging = &nb= sp; The DLP is charging. Screen displays “Charging” when the DLP is plu= gged into the Wall Charger or when it is plugged into the computer via USB cable= but not transferring audio. It is best to leave the DLP plugged into the Wall Charger overnight to ensure a complete charge.
Note: Always fully recharge the DLP before every recording day.

Charged &nb= sp; = The DLP is fully charged and ready to use.

Low Battery = T= he DLP battery is depleted and recording has stopped. The DLP must be connecte= d to the Wall Charger and charged before you continue recording.

Sleeping = &nb= sp; This is the default mode, appears upon power-up when the DLP has no stored audio= . If the DLP is left sleeping for more than 15 minutes, it will automatically tu= rn off and the display screen will be blank.

Recording = &nb= sp; The DLP is recording. Screen displays “Recording” when the ‘REC’ button is pressed and held for 3 seconds. Running recordi= ng time is displayed in hours, minutes and seconds.

Paused &nb= sp; = The DLP is paused. Screen displays “Paused” when RECORD/PAUSE butto= n is pressed and held for 3 seconds during recording. Elapsed recording time is displayed in hours, minutes and seconds. If the DLP is left paused for more than 15 minutes, it will turn off and the display screen will be blank. Pre= ss the POWER on/ off button to turn the DLP on again. It will be in “Paused” mode and you may resume recording by pressing the ‘REC’ button.

<= span style=3D'mso-tab-count:1'> &= nbsp; &nbs= p; &= nbsp; &nbs= p; Note: It is not advisable to pause the DLP for l= ong periods of time during the recording day, such as when a child is napping, because the recording time might total less than 10 hours and no percentile rank information will be given in the reports.

Memory Full = T= he DLP will not hold any more audio data. Screen displays “Memory Full” when the DLP has recorded for 16 continuous hours. When the mem= ory is full, the DLP will turn off after 15 minutes and the display screen will= be blank. DLP will not be able to record more data until current recording is processed.

Audio Transfer = The DLP is connected to the computer via USB cable and the audio is being transferred.

Power Off = &nb= sp; DLP has been powered off by pressing the POWER on/off button for 3 seconds. “Power off” displays briefly on the screen before going blank.<= /p>

Using the DLP

The following procedure explains how to successfully= use the LENA DLP. Always make sure the DLP is fully charged before the recording day. We recommend recording for a full day — from wake-up to bedtime. This will give the most accurate information about a child’s language environment. The DLP can record up to a maxi= mum of 16 hours.

Please follow the instructions below in order for th= e DLP and LENA software to work properly. The Getting Started pamphlet (which is available on www.Infoture.org and www.Lenababy.com) is also available to ai= d in this process. The Getting Started pamphlet can be downloaded, printed and g= iven to off-site users and/or parents of the child using the DLP. These instruct= ions can be used by a professional, a researcher, or given to a parent of a child who has been instructed to use the DLP.

Step 1. Fully charge the LENA DLP before using. This can t= ake up to 3 hours if the battery is drained.

· Connect the DLP to the wall charger using the USB cable.

· The display screen on the LENA DLP should re= ad “Charging.”

· When the battery is fully charged, the displ= ay screen will read “Charged.”

Step 2. Record

· When you’re ready to record, have the = LENA clothing or vest nearby, as you will need to put the DLP into the front poc= ket and dress the child in the clothing immediately after you press the “REC” button.

· Make sure the DLP is on. Press and hold the “REC” button until display screen reads “Recording.” This marks the beginning of the recording.

· Immediately place the DLP into the front poc= ket of the LENA Clothing, snap the pocket closed, and dress the child in the clothing.

Note: To ensure accurate percentile ranking, recording time should exceed 10 hours. The LENA software will not be able to process audio that is less than 10 minutes in length.

Note: If Windows prompts you to format your DL= P, cancel or answer “No.”

Step 3. Remove the DLP from the child’s pocket

· At the end of the day, remove the DLP from t= he child’s LENA clothing pocket, and press the power button to turn the = DLP off.

Step 4. Transfer the audio data

Transferring the audio fi= le moves data from the DLP and stores it onto the computer. LENA software analyzes the audio d= ata, and produces reports. (as des= cribed in Step 5.)

By simply connecting the = DLP to the computer, the LENA software should launch automatically (See Preference= s on the Settings screen for this setting.)&nbs= p; If not, double click the LENA icon on the desktop and connect the DLP again.

The DLP Connect Dialog window will appear. This window allows you to assign a DLP to an existing child or assign a DLP to a new child. You may a= lso view the DLP usage history.

As= sign a DLP to an existing child

1.&n= bsp; Plug in a DLP.

2.&n= bsp; Select the child you want to assign a DLP.

3.&n= bsp; Click the “Assign” button. The c= hild will automatically be assigned to the attached DLP.

Assign a DLP to a new child

1.&n= bsp; Plug in a DLP.

2.&n= bsp; Click the “Add Child” button.

3.&n= bsp; Enter the child first name, last name, birth= date and gender.

4.&n= bsp; Click the “OK” button.

· The Digital Language Processor status screen will open. It may take a few minutes for the computer to identify the DLP. = Once the software verifies that an audio file exists on the DLP, the DLP display should read “Audio Transfer.”

· Audio will automatically begin transferring.=

· The Status column on the Digital Language Processor screen will read “Transferring”. Audio transfer will take approxima= tely 2 to 5 minutes.

· Once the transfer completes, you may disconn= ect the DLP from the computer and recharge it.

Step 5. Processing the audio data

· After the audio has transferred, the software automatically begins processing the file.

· The Status column on the Digital Language Processor screen will read “Processing.”

· Due to the complexity of the LENA software, please allow anywhere from 3 to 16 hours for processing time. Processing ti= me depends on the language environment, computer speed, and processing power.<= /p>

· We recommend allowing the LENA software to process overnight. The software can be set to automatically shut the comput= er down when processing is complete. (See checkbox below the Job List or Preferences on the Settings screen).

· Charge the DLP overnight to prepare for the = next recording day.

· You can upload multiple recordings at one ti= me. When uploading multiple recordings to the computer, each recording is store= d in a queue and will automatically begin processing in the order that they were uploaded.

Step 6. View the LENA Reports

· After processing is complete, click the “LENA Reports” button.

· The Report List opens by default.

· The following reports are available: Adult Words, Conversational Turns, Child Vocalizations, Audio Environment, Compos= ite View and Report List.

· Navigate through the reports easily by selec= ting the appropriate box located at the bottom of the screen.

· Report information can be viewed using 4 modes: Monthly, Daily, Hourly= and 5-minute.

· Roll over features allow you to see addition= al information, such as Estimated Mean Length of Utterance (EMLU) and Standard Score compared to human assessments.

Adult Words

The Adult Words Report provides feedback abou= t the key child’s language environment.&nb= sp; As the software processes the recorded audio file algorithmically, t= he number of Adult Words spoken to the child during the course of a 10 to 16-h= our recording session are segmented and counted. The Adult Word Counts are plotted = on a chart for easy viewing.

Figure L. Adult Words report = on a monthly time scale

Figure M. Adult Words report on the 5-minute time scale

How to Read the Adult Words Report

The y-axis displays the total number of adult words = spoken per unit time period. The x-a= xis displays the dates for which data exists (in monthly, daily, hourly, or 5 minute increments). Rolling the cursor over any data bar will present you w= ith a tool tip providing more detailed statistics^[1]. Right-click on any 5-minute segmen= t to Play, Export, Mark or add Notes to the audio for that segment.

Conversational Turns

The Conversational Turns (CT) Report provides estimates of the total number of conversational interactions the child enga= ges in with an adult within a 5-second interval. Overlapping speech segments, cough= s, cries, and other vegetative and fixed signals do not contribute to the Conv= ersational Turns estimate.

How to Read the Conversational Turn Report

The y-axis displays the average number of conversati= onal turns per day during the month. The x-axis displays the months for wh= ich there is data. The most recent month is the last data point on the progression line. Similar to the Adult Word Report, rolling over a da= ta bar or point will present you with a tool tip providing more detailed statistics. Right-click on any 5-minute segment to Play, Export, Mark or add Notes to the audio for that segment.

Tracking Possible Language Delays

If there is a possible language delay, a yellow data point will appear on the Conversational T= urns Daily report. A yellow and blue data point will appear in the Conversational Turns Monthly report. (See Figure N.) This feature is not available in any other of the LENA Reports.

Conversational Turns Monthly: Possible Language Delay

: When the yellow and blue Possible Language Delay data point appears in the CT Monthly report, it signifies that there was one or more days in the daily view that were flagg= ed as Possible Delay.

Figure N. Composite View (Monthly) with possible language delay data

Conversational Turns Daily: Possible Language Delay

: When the yellow Possib= le Language Delay data point appears in the CT Daily report, it signifies = that there is a possible language delay detected in that day.

Figure O. Composite View report (daily view): Possible language delay data point shown in Conversational Turns section. (Yellow data points)

Rollover Tool

What is shown in the Rollover Tool varies with each re= port. In the Conversational Turns report (daily view) the following features appl= y:

·   Average scores are shown only if they are available

·   AVA information (Standard Score, EMLU and Developmental Age) will be available

·   If you have not met the 3-day recording criteria, Average Score will not be displayed

If there is a Possible Language Delay, the Conversatio= nal Turns (monthly view) Rollover Tool will not report specific AVA information. Instead, the tool will display “Possible Language Delay” in red. (See image below)
