Practical overview
When it fits
Use NeuralSP when you need an implementation-oriented starting point for end-to-end ASR or language-model experiments and can work with its Python/PyTorch code and Kaldi-related setup.
Who it is for
- Researchers comparing end-to-end ASR architectures and decoding approaches.
- Developers training speech-recognition or language models on the corpora named by the project.
- Practitioners exploring streaming-oriented recognition mechanisms or language-model fusion.
Documented uses
- Prototype ASR systems using CTC, RNN-transducer, or attention-based decoding.
- Compare RNN, Transformer, Conformer, and convolutional encoder designs.
- Train or evaluate models using supported speech and text corpora.
- Experiment with recurrent, convolutional, or Transformer-based language models.
Requirements & limits
The repository is public and identifies its license as Apache-2.0.
- The README lists a broad set of ASR encoders and CTC, RNN-transducer, and attention-based decoders, so it suits architecture comparisons.
- The documented setup command requires a Kaldi path and tools destination; factor this tooling into setup planning.
- Corpus support is specified by name, including Librispeech, Switchboard, TEDLIUM, Penn Tree Bank, and WikiText2.
- Reported benchmark tables are tied to listed datasets and configurations; they do not establish performance for a different experiment.
Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.
Prepare NeuralSP’s Kaldi-related tools
Run the documented installation command to set the Kaldi location and tools destination.
Before you start
- A checkout of the NeuralSP repository
- A Kaldi installation and its path
- A destination path for the tools
Steps
Open a shell in the repository’s tools directory.
Run the command below, replacing the placeholder paths with the relevant locations.
make KALDI=/path/to/kaldi TOOL=/path/to/save/tools
Expected outcome
The documented tools installation command has been invoked with paths for Kaldi and the tools destination.
Guide limitations
- No execution or compatibility test is claimed.
