pymbrola
A Python interface for the MBROLA speech synthesizer, enabling programmatic creation of MBROLA-compatible phoneme files and automated audio synthesis. This module validates phoneme, duration, and pitch sequences, generates .pho files, and can call the MBROLA executable to synthesize speech audio from text-like inputs.

Features
- Front-end to MBROLA: Easily create
.phofiles and synthesize audio with Python. - Input validation: Prevents invalid file and phoneme sequence errors.
- Customizable: Easily set phonemes, durations, pitch contours, and leading/trailing silences.
Requirements
- Python 3.10+
- MBROLA binary installed and available in your system path, or via WSL for Windows users.
- MBROLA voices (e.g.,
it4) must be installed at/usr/share/mbrola/<voice>/<voice>.
To install MBROLA in your Ubuntu or WSL instance, run the [mbrola/install.sh] script:
sudo bin/install.sh --voice fr2 it4 # install voices fr2 and it4
sudo bin/install.sh --voice all # install all voices
sudo bin/install.sh # install no voices
Installation
MBROLA is currently available only on Linux-based systems like Ubuntu, or on Windows via the Windows Susbsystem for Linux (WSL). Install MBROLA in your machine following the instructions in the MBROLA repository. If you are using WSL, install MBROLA in WSL. After this, you should be ready to install pymbrola using pip.
pip install mbrola
Usage
import mbrola
# Create an MBROLA object
caffe = MBROLA(
phon=["k", "a", "f", "f", "E1"],
durations=100, # or [100, 120, 100, 110]
pitch=[100, [200, 50, 200], 100, 100, 200],
)
# Display phoneme sequence
print(caffe)
# Export PHO file
caffe.export_pho("caffe.pho")
# Synthesize and save audio (WAV file)
caffe.make_sound("caffe.wav", voice="it4")
The module uses the MBROLA command line tool under the hood. Ensure MBROLA is installed and available in your system path, or WSL if on Windows.
Troubleshooting
- Ensure MBROLA and the required voices are installed and available at
/usr/share/mbrola/<voice>/<voice>. - If you encounter an error about platform support, make sure you are running on Linux or WSL.
- Write an issue, I'll look into it ASAP.
