Top 10 C++ speech-recognition Projects

Project mention: Building a personal, private AI computer on a budget | news.ycombinator.com | 2025-02-11
A great thread with the type of info your looking for lives here: https://github.com/ggerganov/whisper.cpp/issues/89
But you can likely find similar threads for the llama.cpp benchmark here: https://github.com/ggerganov/llama.cpp/tree/master/examples/...
These are good examples because the llama.cpp and whisper.cpp benchmarks take full advantage of the Apple hardware but also take full advantage of non-Apple hardware with GPU support, AVX support etc.
It’s been true for a while now that the memory bandwidth of modern Apple systems in tandem with the neural cores and gpu has made them very competitive Nvidia for local inference and even training.

DeepSpeech
DeepSpeech is an open source embedded (offline, on-device) speech-to-text engine which can run in real time on devices ranging from a Raspberry Pi 4 to high power GPU servers.
Project mention: ESpeak-ng: speech synthesizer with more than one hundred languages and accents | news.ycombinator.com | 2024-05-01As I understand it DeepSpeech is no longer actively maintained by Mozilla: https://github.com/mozilla/DeepSpeech/issues/3693
For Text To Speech, I've found Piper TTS useful (for situations where "quality"=="realistic"/"natual"): https://github.com/rhasspy/piper
For Speech to Text (which AIUI DeepSpeech provided), I've had some success with Vosk: https://github.com/alphacep/vosk-api
