kaldi-asr/kaldi

An open-source toolkit for building speech recognition systems, written in C++ with example builds for developers and researchers. It runs on UNIX-like platforms with cross-compilation support for Android and WebAssembly, though it requires compiling from source and installing specific development dependencies.

Best for

Developers and researchers who need to build and compile speech recognition systems from C++ source code on UNIX platforms.
Projects requiring cross-platform compilation targeting Android or WebAssembly environments.

Key capabilities

A toolkit designed for building speech recognition systems.
Provides example system builds that can be run by users to test or baseline speech recognition implementations.
Supports cross compiling for Android using Android NDK, clang++ and OpenBLAS for mobile deployments.
Supports cross compiling for Web Assembly for in-browser execution using emscripten and OpenBLAS.

Limitations and risks

Users will likely encounter problems during the build process due to dependency and compilation requirements.
The toolkit has not been tested on more exotic varieties of UNIX, which may cause compatibility issues on unsupported systems.

Getting started

Setup is considered hard; users must read the ./INSTALL file, install specific dependencies like lapack-devel and openfst-devel, and run cmake configuration and build commands.
