IBM has released [Granite Speech 5.0](https://huggingface.co/blog/ibm-granite/granite-speech-5), the latest entry in its Granite family aimed at speech understanding. The model is built for three core tasks: transcribing audio, translating it, and attributing speech to individual speakers—all under a permissive Apache-2.0 license.

## What it does

According to IBM, the release focuses on three capabilities:

- **Transcription** — turning spoken audio into text
- **Translation** — converting speech across languages
- **Speaker attribution** — identifying who said what in a recording

IBM frames the update around doing all of this "more accurately and faster," positioning speaker attribution as a notable addition. That last feature matters for real-world audio like meetings, interviews, and call-center logs, where knowing the speaker is often as important as the words themselves.

## Why it matters

Open, commercially usable speech models remain comparatively scarce next to the flood of open text models. By shipping Granite Speech 5.0 under Apache-2.0, IBM gives developers a foundation they can deploy and fine-tune without licensing friction. The combination of transcription, translation, and attribution in one model is convenient for teams that would otherwise stitch together separate tools.

Full details, including supported languages and performance claims, are available in IBM's [announcement on Hugging Face](https://huggingface.co/blog/ibm-granite/granite-speech-5).
