Understand the project

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.
Before you choose

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.

Source-based practical guide

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

  1. Open a shell in the repository’s tools directory.

  2. Run the command below, replacing the placeholder paths with the relevant locations.

    Documented command
    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.
