Overview

This is an implementation of whisper from scratch in C++. This is a proof-of-concept. Further modifications, imporvements are coming.

Feedbacks are wellcomed in the corresponding github repository, precompAId.

Binary contains:

• exe for testing the app quickly
• header and dll for building custom solutions
• main.cpp as an example, how to use the header (the exe compiled from this)
• weights.xdf (required to load into the graph, no other input required)
• audios folder, containing examples to try the application
• convert.py for creating the right input for the application from and arbitrary audio file

Quick start

Example for the usage of whisper.exe (dll should be discoverable by the exe):

whisper.exe weights.xgdf audios\voice_example1.pb

Example compilation (with clang from the root):

clang++ main.cpp win64\whisper.lib -o whisper.exe

Example for converting:

python convert.py --ipath audios\voice_example_orig1.wav --opath voice_example.pb

Implementation info

Tested on:

• windows 11
• intel i7 11th gen
• clang 16.06 as compiler

Current properties:

• fp32
• avx512 is required
• this tool can help enlisting the available cpu features

Further Notes

Improved versions will arrive regularly. Feedbacks are wellcomed. Especially the following:

• features to be add (input format, expected output format etc.)
• devices (plan to extend for mobiles, IPUs etc.)
• models (what other models would be great to accelerate)
