Unlimited conversations in the classroom.


DiLL’s intuitive connection based concept makes it easy to create discussion groups of any size, designate model student(s), pair students randomly, all while maintaining the versatility to speak with individuals, groups, or the entire class.

Randomly Group creates pairs or groups of any size instantly.

DiLL chooses the most distant partners to discourage non-verbal communication, and won't repeat previous pairings.
Broadcast your voice to the entire class, temporarily muting any conversations in progress.
See who is talking to whom, and modify speaking activities on the fly.

Simple connection concept.


A voice connection causes sound to flow from one person to another (in the direction of the arrow), and can be created simply by dragging a line.

One-way connections allow surreptitious monitoring, while two-way connections create conversations. And broadcasting, conveniently, is simply monitoring in reverse.

Connect students many ways.
Be creative.


Choose exactly which students to pair together, or put them in automatically-randomized groups of any size. Teachers can monitor and speak privately either to individual students to correct them on drills, or with groups of students to facilitate their conversations.

Students can monitor each other while simultaneously being monitored by others.

By combining multiple connections between multiple students, any speaking activity is possible.

An interface teachers love to use.


DiLL presents the teacher with a simple visual interface for viewing and managing the classroom. Students are represented as arrangeable objects mapped to their physical presence in the room. These student objects can be easily manipulated with drag-and-drop actions. Teachers see live updates of student progress and can listen in to speech in real time.

Use the familiar undo command to restore a previous activity or set of speaking partners.
Distribute audio lessons selectively by dragging a "task" onto one or more students.
Arrange the live visual map by the physical layout of the classroom or by conversational groups.
View the current lesson on which students are working as well as whether they are playing or recording.
View thumbnail images of student screens that are updated in real-time as students work.

A smart media player for self-guided lessons.


By recording in discrete segments and automatically recognizing unnecessary silence, the DiLL student player provides precise control over audio lessons. Students can replay and re-record their responses to audio stimuli until they're satisfied with the result. And by slowing down lesson audio without changing the pitch, students can more easily tackle rapid-fire native speech.

Best of all, DiLL is compatible with all standard audio formats. Import audio content from existing textbook CDs and resources online, or record your own audio lesson materials.

Students can request teacher attention for private one-on-one instruction.
Students can insert as many recordings as they want, at any point, into a lesson.

Any audio can be used for a lesson, even if the audio files lacks any pre-recorded silence.
Automatically replay the last word or phrase in the lesson.
Navigate the lesson visually using graphical indicators that differentiate between spoken and silent sections.
Students can signal availability for self-initiated grouping and be paired automatically with other available students.

Teachers have the option of making students anonymous to each other.

Centralized organization and management of files.


DiLL saves student recordings automatically to a school-hosted central server, organized by the student's name and the teacher's lesson — so users never have to worry about saving files and emailing them to each other. Because files are hosted centrally, teachers can access student work by logging into the DiLL server from any web browser, either at school or remotely from home.

Log-in with the same school username and password you know.
Zip all student recordings into one convenient file for download.
Hear all student recordings all at once or play them one at a time.
Teachers can listen to students' recordings by visiting the DiLL server over the web, at school or remote from home. Compatible with all major browsers.
Student recordings are organized by teacher, lesson, and the student's name.
