Now let’s also install the Python libraries we’ll need to get this to work. Sox can be installed by using either ‘apt’ for Ubuntu/Debian or ‘dnf’ for Fedora as shown below. If you’re using a Unix distribution, you’ll need to install Sound eXchange (sox).

Let’s go through some example code on how to asynchronously transcribe speech with DeepSpeech. wav files are supported as of late September 2021.

# Download pre-trained English model filesĪ quick heads up - when using DeepSpeech, it is important to consider that only 16 kilohertz (kHz). Notice that the files we’re downloading below are the ‘.scorer’ and ‘.pbmm’ files. If you have cURL installed, you can download DeepSpeech’s pre-trained English model files from the DeepSpeech GitHub repo as well. As discussed in our overview of Python Speech Recognition in 2021, you can download, and get started with, DeepSpeech using Python’s built-in package installer, pip. Basic DeepSpeech ExampleĭeepSpeech is easy to get started with.
In the below tutorial, we’re going to walk you through installing and transcribing audio files with the Mozilla DeepSpeech library (which we’ll just refer to as DeepSpeech going forward). Another cool feature is the ability to contribute to DeepSpeech’s public training dataset through the Common Voice project. Today, the Mozilla DeepSpeech library offers pre-trained speech recognition models that you can build with, as well as tools to train your own DeepSpeech models. In addition, the theory introduced by the Baidu research paper was that training large deep learning models, on large amounts of data, would yield better performance than classical speech recognition models. The goal of “end-to-end” models, like DeepSpeech, was to simplify the speech recognition pipeline into a single model. This is compared to traditional speech recognition models, like those built with popular open source libraries such as Kaldi or CMU Sphinx, that predict phonemes, and then convert those phonemes to words in a later, downstream process. “End-to-end” means that the model takes in audio, and directly outputs characters or words. The original DeepSpeech paper from Baidu popularized the concept of “end-to-end” speech recognition models. In 2017, Mozilla created an open source implementation of this paper - dubbed “ Mozilla DeepSpeech”. What is DeepSpeech? DeepSpeech is a neural network architecture first published by a research team at Baidu.
