Here’s A Plain C/C++ Implementation Of AI Speech Recognition, So Get Hackin’

[Georgi Gerganov] recently shared a great resource for running high-quality AI-driven speech recognition in a plain C/C++ implementation on a variety of platforms. The automatic speech recognition (ASR) model is fully implemented using only two source files and requires no dependencies. As a result, the high-quality speech recognition doesn’t involve calling remote APIs, and can run locally on different devices in a fairly straightforward manner. The image above shows it running locally on an iPhone 13, but it can do more than that.

Implementing a robust speech transcription that runs locally on a variety of devices is much easier with [Georgi]’s port of OpenAI’s Whisper.
[Georgi]’s work is a port of OpenAI’s Whisper model, a remarkably-robust piece of software that does a truly impressive job of turning human speech into text. Whisper is easy to set up and play with, but this port makes it easier to get the system working in other ways. Having such a lightweight implementation of the model means it can be more easily integrated over a variety of different platforms and projects.

The usual way that OpenAI’s Whisper works is to feed it an audio file, and it spits out a transcription. But [Georgi] shows off something else that might start giving hackers ideas: a simple real-time audio input example.

By using a tool to stream audio and feed it to the system every half-second, one can obtain pretty good (sort of) real-time results! This of course isn’t an ideal method, but the robustness and accuracy of Whisper is such that the results look pretty great nevertheless.

You can watch a quick demo of that in the video just under the page break. If it gives you some ideas, head over to the project’s GitHub repository and get hackin’!

  1. I remember when some folks made AI that learned voices of polish voice actours from Gothic II game. Then they used this AI to dub very vulgar adult movies. Original voice actours go angered so hardly that they sued for damage and even got those poor nerds imprisoned for improper use of AI.

  2. That’s so awesome. I’ve always wanted a voice controlled computer assistant, but I will never, ever install some closed source, monetized, “we send everything you say to our servers” wiretap.

    Maybe this technology has finally disseminated enough that that can be done without a PHD in artificial intelligence.

  3. Works like a charm on Debian 11 running on an AMD Ryzen 7 5700G. I tested all of the examples and it was perfect, not a single issue. Many thanks to all those involved in the project.

    1. Wish I could say the same for the AVX2 version running on an 8th gen core i7. Consistently 10x slower than the Apple ARM metrics given in the README. Real time dictation = forget it! Still a nice piece of work. Maybe it’s a sign I should switch to an M2.

      1. Try building it under Clear Linux? That is Intel optimised. I forgot to mention I am using the 6.1.0-0-amd64 Linux kernel. Also play with the -t option I found 8 threads was optimal even when I have 16 cores.
