Frikallo/parakeet.cpp
Ultra fast and portable Parakeet implementation for on-device inference in C++ using Axiom with MPS+Unified Memory
Supports multiple decoder types (CTC, TDT, RNNT) with optional beam search and ARPA language model fusion, plus phrase boosting for domain-specific vocabulary. Built entirely in C++ on axiom's Metal tensor compiler without external runtimes—encoder inference fuses into optimized MPSGraph operations. Offers streaming models with configurable latency, speaker diarization, VAD preprocessing, and multi-format audio (WAV/FLAC/MP3/OGG) with a flat C API for FFI bindings to Python, Swift, Go, and Rust.
