DeepSpeech is an open source Speech-To-Text engine, using a model trained by machine learning techniques. It’s a TensorFlow implementation of Baidu’s DeepSpeech architecture.
This open-source platform is designed for advanced decoding with flexible knowledge integration.
The software is in an early stage of development.
The core of the system is a bidirectional recurrent neural network (BRNN) trained to ingest speech spectrograms and generate English text transcriptions. A pre-trained English model is available for use.
The software needs Python 2.7, and the Git Large File Storage – a Git extension for versioning large files.
Key Features
- 3 different ways to use the software:
- Python package.
- Command-line client.
- Node.JS package.
- Works with signed 16-bit PCM data.
- Takes word lattice as input, perform feature extraction specified by developers, generate factor graphs based on descriptive rules, and perform learning and inference automatically.
Supported operating systems:
- OS X 10.10, 10.11, 10.12 and 10.13
- Linux x86 64 bit with a modern CPU (needs at least AVX/FMA)
- Linux x86 64 bit with a modern CPU + NVIDIA GPU (Compute Capability at least 3)
- Raspbian Jessie on Raspberry Pi 3
