ClassTrace.
In Indian colleges, professors explain core engineering in Hinglish, Tamil, Telugu, and mixed dialects. ClassTrace indexes the entire lecture, catches your spoken doubts in any tongue, and jumps directly to the professor's original explanation.
“Sir ne recursion ka base case kaise samjhaya tha?”

Timbre v2.5Beta
Speaks 10+ Indic languages with context-aware prosody, Indian names, numerals and lakh and crore cadence. Streams over WebSocket and SSE.
Evon v3.330B MoE
A 30B-parameter mixture-of-experts model with 128K context and 11 Indian languages natively. Apache 2.0 weights are available by request on Hugging Face.
Why Generic Tools Fail in Indian Classrooms
1-Hour Recordings are Too Long
Students miss a 2-minute explanation of recursion or database normalization. Nobody has time to rewatch an entire 60-minute recording the night before exams.
Regional Code-Mixing Reality
Professors don't speak pure Oxford English. They explain complex DSA and core engineering concepts in Hinglish, Tanglish, or Tenglish. Standard speech tools choke on technical loanwords.
Fabricated Summaries Fail
Text-generation LLMs fabricate formulas and guess exam answers. ClassTrace plays the teacher's exact speech directly from the audio recording.
How ClassTrace Works
Record Live Class
Hit Record in the classroom. ClassTrace captures audio, standardizes to 16kHz mono WAV via FFmpeg, and stores it permanently.
Gnani Pan-Indic STT
Batch speech-to-text transforms the lecture into precise segments with word-level timestamps and acoustic peaks.
Student Spoken Question
Ask by voice: “Sir ne recursion ka base case kaise explain kiya?” Transcribed with automatic dialect detection.
Direct Audio Playback
Multilingual vector search matches the question against the exact lecture moment and plays the teacher's own words with karaoke highlighting.
