## Decision facts: whisper-timestamped

- **Adopt for:** whisper-timestamped is a Python library that extends OpenAI's Whisper model with word-level timestamps and confidence scoring.

## Choose when

### Choose whisper-timestamped if…

- License: whisper-timestamped is AGPL-3.0, dia2 is Apache-2.0.
- Tags unique to whisper-timestamped: asr, attention-mechanism, deep-learning, multilingual-models.
- whisper-timestamped ships Docker support for self-hosted deployment.
- When you need precise timestamping for each spoken word in speech recognition output.

### Choose dia2 if…

- License: dia2 is Apache-2.0, whisper-timestamped is AGPL-3.0.
- Tags unique to dia2: open-weight, text-to-speech.
- When you need real-time streaming capabilities for text-to-speech applications.

## When NOT to use whisper-timestamped

- Avoid if your project requires minimal dependencies or a smaller footprint, as it includes several external libraries like matplotlib and transformers.
- Not suitable for real-time applications where low latency is crucial due to the additional overhead of timestamp generation and confidence scoring.

## When NOT to use dia2

- For projects aimed at batch processing or non-realtime TTS applications where instantaneous audio output isn't required.
- If you are looking for an open-source model that does not include specific proprietary components like the Kyutai Mimi codec.
