LENA Online is the secure web-based portal at https://o.lena.org where logged-in users carry out most of their LENA tasks. Users log in to:

• manage participants and groups
• enter recorder assignments
• see and print reports and data summaries
• check dashboards for data alerts
• access LENA Resources
• export data

LENA Online runs on the Google Chrome web browser and is best accessed via a computer. Some features may not work optimally on a tablet.

LENA Hub is the device transfer software. Its job is to remove LENA Day data from the devices and then send the data to the cloud to be converted into reports for LENA Online. LENA Hub can also be used to erase junk data off of the devices and to reset their clocks. 

LENA Hub does not:

• allow data to be played back
• display LENA Day data
• have a data management/data entry portal

LENA Hub must be installed on at least one Windows computer that is connected to the Internet for device transfers. The computer must meet or exceed the specifications described in the LENA Grow System Components and Requirements document.

The LENA Hub installer can be downloaded from the Resources section of LENA Online (login required). After installation, it is accessed in the same way as other Windows programs - by a desktop shortcut icon, via the Windows start menu, or through a pinned taskbar icon.

The LENA Device Service is a helper program that automatically installs with the LENA Hub and runs in the background to facilitate communication between the LENA Hub program and connected LENA devices.

The Multi Dock is a powered USB station. It is an accessory used to connect your LENA devices to your LENA Hub computer for transfer and to charge them for the next use. It makes data transfers fast and efficient!  

The Multi Dock has:

• 10 USB ports that provide the correct amperage to charge your devices (some models have 7 ports)
• USB cords to connect the devices
• a USB cord to connect to the LENA Hub computer, allowing the program to communicate with all connected devices
• a power cord to plug into an electrical outlet

The Multi Dock must be connected to a power source and to the LENA Hub computer for data transfers.

When not being used for data transfer, it can be disconnected from the computer but left plugged in to power to charge the connected devices.

The LENA device is a lightweight but sophisticated data collection tool. Placed inside the chest pocket of specially designed LENA clothing worn by a LENA participant, it can capture a full day of the child's classroom language environment.

The device does not:

• play back audio
• contain a listenable file
• recognize words
• transmit a signal
• like to be put in water

A LENA user connects the device to the LENA Hub computer via the Multi Dock (or directly via USB cord) to transfer the data for processing and deletion.

While not exactly a piece of tech, the LENA clothing is specially designed and tested to work with the LENA device.

Worn over the child's regular clothing, it securely positions the device at an appropriate distance from the child's mouth. This placement ensures that LENA's processing algorithms can identify vocalizations produced by that child and differentiate these from other children's speech. This is key to detecting those conversational turns!  

Soft fabric and light padding ensure that the clothing does not interfere with data collection, while strong snaps help prevent the device from "escaping." The clothing is comfortable and machine washable.
