Current State
The current public Article should be updated from this file and treated as the single running-notes Article for Voice Reach. The older supporting Article URL remains published provenance, but its content now belongs here instead of in a separate local article source.
Hosted proof should be read narrowly: Voice Reach has a private Space package,
trace surfaces, and recorded model/runtime smoke evidence. A fresh public
submission claim still needs a current hosted run with fallback_used=false.
Notes
2026-06-15 - Model And Runtime Note
The current decision signal is Nemotron ASR plus explicit language hint for ASR, with tiny-aya fire as the best current Hindi/Hinglish text default. MiniCPM5 remains useful for English smoke/default fallback. Cohere official ASR should stay deferred until a comparison smoke is worth a paid Modal redeploy and live run.

Model decision snapshot:
| Role | Model | Runtime Shape | Finding |
|---|---|---|---|
| ASR | onnx-community/nemotron-3.5-asr-streaming-0.6b-onnx-int4 |
ONNX / NeMo-style ASR path | Best current ASR signal with explicit language hint. |
| ASR | onnx-community/cohere-transcribe-03-2026-ONNX |
Intended Transformers.js/WebGPU; current Python path unsupported | Selector-visible, but current Modal endpoint returns an explicit adapter blocker instead of fake output. |
| ASR | CohereLabs/cohere-transcribe-03-2026 |
Transformers | Adapter call shape was corrected, but no redeployed live proof is counted yet. |
| Text | openbmb/MiniCPM5-1B-GGUF |
llama.cpp / GGUF | Runnable hosted proof exists; useful as English smoke/default fallback. |
| Text | CohereLabs/tiny-aya-fire-GGUF |
llama.cpp / GGUF | Best current Hindi/Hinglish text signal, with higher latency. |
| Text | nvidia/NVIDIA-Nemotron-3-Nano-4B-GGUF |
llama.cpp / GGUF | Runnable but weak on the current seed set. |
What ran:
- Corrected the official Cohere ASR comparison adapter to the HF model-card call shape.
- Generated a privacy-safe agent trace bundle with 36 hosted trace rows.
- Uploaded the private Space to
build-small-hackathon/voice-reach. - Uploaded the private trace dataset to
build-small-hackathon/voice-reach-agent-traces.
What this proves:
- The Article/dataset bundle carries privacy-safe hosted trace rows and schema.
- Nemotron ASR with explicit language hint is the best current ASR signal.
- tiny-aya fire is the best current Hindi/Hinglish text signal.
What this does not prove:
- Broad ASR quality across real traffic.
- Production email delivery.
- Judge-ready status.
- Cohere official ASR proof after the adapter correction.
