SoundChoice: Grapheme-to-Phoneme Models with Semantic Disambiguation

This repository provides all the necessary tools to perform English grapheme-to-phoneme conversion with a pretrained SoundChoice G2P model using SpeechBrain. It is trained on LibriG2P training data derived from LibriSpeech Alignments and Google Wikipedia

Install SpeechBrain

First of all, please install SpeechBrain with the following command (local installation):

git clone https://github.com/speechbrain/speechbrain
cd speechbrain
pip install -r requirements.txt
pip install -e .

Please notice that we encourage you to read our tutorials and learn more about SpeechBrain.

Perform G2P Conversion

Please follow the example below to perform grapheme-to-phoneme conversion with a high-level wrapper.

from speechbrain.pretrained import GraphemeToPhoneme
g2p = GraphemeToPhoneme.from_hparams("speechbrain/soundchoice-g2p")
text = "To be or not to be, that is the question"
phonemes = g2p(text)

Given below is the expected output

>>> phonemes
['T', 'UW', ' ', 'B', 'IY', ' ', 'AO', 'R', ' ', 'N', 'AA', 'T', ' ', 'T', 'UW', ' ', 'B', 'IY', ' ', 'DH', 'AE', 'T', ' ', 'IH', 'Z', ' ', 'DH', 'AH', ' ', 'K', 'W', 'EH', 'S', 'CH', 'AH', 'N']

To perform G2P conversion on a batch of text, pass an array of strings to the interface:

items = [
    "All's Well That Ends Well",
    "The Merchant of Venice",
    "The Two Gentlemen of Verona",
    "The Comedy of Errors"
transcriptions = g2p(items)

Given below is the expected output:

>>> transcriptions
[['AO', 'L', 'Z', ' ', 'W', 'EH', 'L', ' ', 'DH', 'AE', 'T', ' ', 'EH', 'N', 'D', 'Z', ' ', 'W', 'EH', 'L'], ['DH', 'AH', ' ', 'M', 'ER', 'CH', 'AH', 'N', 'T', ' ', 'AH', 'V', ' ', 'V', 'EH', 'N', 'AH', 'S'], ['DH', 'AH', ' ', 'T', 'UW', ' ', 'JH', 'EH', 'N', 'T', 'AH', 'L', 'M', 'IH', 'N', ' ', 'AH', 'V', ' ', 'V', 'ER', 'OW', 'N', 'AH'], ['DH', 'AH', ' ', 'K', 'AA', 'M', 'AH', 'D', 'IY', ' ', 'AH', 'V', ' ', 'EH', 'R', 'ER', 'Z']]

Inference on GPU

To perform inference on the GPU, add run_opts={"device":"cuda"} when calling the from_hparams method.


The SpeechBrain team does not provide any warranty on the performance achieved by this model when used on other datasets.


The model was trained with SpeechBrain (aa018540). To train it from scratch follows these steps:

  1. Clone SpeechBrain:

    git clone https://github.com/speechbrain/speechbrain/
  2. Install it:

    cd speechbrain
    pip install -r requirements.txt
    pip install -e .
  3. Run Training:

    cd recipes/LibriSpeech/G2P
    python train.py hparams/hparams_g2p_rnn.yaml --data_folder=your_data_folder

Adjust hyperparameters as needed by passing additional arguments.
