Practical overview
When it fits
Use CrispASR when you want a shared C++ runtime and CLI for multiple supported speech-model backends, or an integration interface such as its HTTP server or language bindings.
Who it is for
- Developers building speech features into software through a CLI, HTTP server, C ABI or language bindings.
- People who need to transcribe audio, generate speech or perform supported speech-to-text translation with selectable model backends.
Documented uses
- Transcribe audio with a supported speech-recognition model.
- Generate speech from text with a supported TTS backend.
- Request word-level timestamps or forced alignment for audio and text.
- Translate speech into text in another language with a supported model.
- Integrate speech processing into an application through documented interfaces.
Requirements & limits
The repository is public and specifies an MIT license. The README documents CLI usage and a browser WebAssembly build; the browser build requires COOP/COEP headers.
- A compatible model file is required for the model-driven workflows; model formats and acquisition steps vary by backend.
- The documented capabilities differ by backend: examples include Parakeet transcription and word timestamps, Canary speech translation, and Kokoro text-to-speech.
- The README lists platform-specific prebuilt binaries and GPU build variants; it notes that some GPU variants require matching drivers and do not fall back to CPU.
- The browser WebAssembly option is described as client-side and requires COOP/COEP headers.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Transcribe audio with a Parakeet GGUF model
Run a transcription using the documented Parakeet model and sample audio.
Before you start
- A CrispASR binary built for the user's platform.
- A shell with curl available.
- The documented Parakeet GGUF model file and an audio file at samples/jfk.wav, or a substitute audio file.
Steps
Download the quantized Parakeet model using the documented curl command and model URL.
Run crispasr with the model file and audio file: ./build/bin/crispasr -m parakeet.gguf -f samples/jfk.wav.
For word-level timestamps, add the documented -ml 1 option.
Expected outcome
The documented workflow produces a transcription; with -ml 1 it requests word-level timestamps.
Guide limitations
- The example assumes the CrispASR binary and sample audio are available at the shown paths.
- The source documents an example workflow, not a guarantee of results for other audio or model files.
