ds-transcriber
A deepspeech powered utility for transcribing a microphone stream
Prelude
You can think of this crate as a wrapper for RustAudio’s deepspeech-rs. It aims to provide transcription for microphone audio with optional denoising.
Getting Started
This example shows the quickest way to get started with ds-transcriber.
First, add ds-transcriber to your Cargo.toml
ds-transcriber = "1"
Download the DeepSpeech native client and then add its directory to your LD_LIBRARY_PATH
and
LIBRARY_PATH
variables.
Have a look at StreamSettings to fine tune the transcription stream to parameters that better suite your environment
let mut model = ds_transcriber::model::instance_model(
"model_file.pbmm",
Some("scorer_file.scorer"),
)?;
let config = ds_transcriber::StreamSettings::default();
let i_said = ds_transcriber::transcribe(config, &mut model)?;
println!("I said: {}", i_said);
Rinse and repeat the last two lines
Features
This crate provides an optional feature of denoising of the audio stream (may result in better
transcription). It is disabled by default, to enable it: use either the denoise
or full
key
in the crate’s features list
ds-transcriber = { version = "1", features = ["denoise"] } # or features = ["full"]
Crate example
Clone the repository and run the example
For help with arguments, run:
cargo run --example transcribe -- -h
To start the example, run
cargo run --example transcribe -- -m model_file -s scorer_file -c deepspeech_native_client_dir
The s
or --scorer
argument is optional, but it is recommended to set one.
Re-exports
This crate also re-exports the deepspeech
and nnnoiseless
crates (if the denoise
feature is enabled). You can use these re-exports instead of also depending on them separately.
Re-exports
pub use deepspeech;
