About
voxtral.c is a pure C implementation of the inference pipeline for the Mistral AI's Voxtral Realtime 4B speech-to-text model, designed for real-time speech recognition. It boasts zero external dependencies beyond the C standard library, making it highly portable and efficient. The tool supports various input methods, including WAV files, live microphone input (macOS), and streaming audio from stdin, allowing for transcription of virtually any audio format via ffmpeg. Key features include Metal GPU acceleration for Apple Silicon, streaming output of tokens as they are generated, a streaming C API for incremental audio processing, and memory-mapped BF16 weights for near-instant loading. It also incorporates a chunked encoder and rolling KV cache to manage memory usage efficiently, enabling unlimited-length audio transcription.
