Elpis (Accelerated Transcription)

Build Status Coverage Status

This project is under construction and not yet ready for everyday use. Please contact us by email at to be informed when a stable version is ready.

Elpis is a tool which allows language workers with minimal computational experience to build their own speech recognition models to automatically transcribe audio. It relies on the Kaldi automatic speech recognition (ASR) toolkit. Kaldi is notorious for being difficult to build, use and navigate - even for trained computer scientists. The goal of Elpis is to expose the power of Kaldi to linguists and language workers by abstracting away much of the needless technical complexity.
