In today’s blog, we’re diving into the intriguing world of text-to-speech (TTS) technology! Specifically, we’ll explore the Hausa language TTS model developed under Facebook’s Massively Multilingual Speech (MMS) initiative. This repository is designed to help you synthesize spoken Hausa text easily and efficiently. Let’s go step-by-step on how to get started!

1. Getting Started

You must first set the stage before you can put this powerful model to work. Follow these steps to get everything in order:

• Ensure you have Python installed.
• Make sure you are using transformers version 4.33 or higher.

2. Installing the Transformers Library

To harness the capabilities of this TTS model, you’ll need to install the latest version of the Transformers and Accelerate libraries. Open your terminal and run:

pip install --upgrade transformers accelerate

3. Running the Hausa TTS Model

Now that the necessary libraries are in place, you can run inference with the Hausa TTS model. For this, you’ll use a Python script that we will break down.

Imagine the TTS model as a sophisticated translator, not just converting text to sound but also interpreting the emotion and rhythm of the language. It’s akin to a chef following a recipe. The text is the list of ingredients, the model is the chef, and the speech output is the delightful dish served at the end! Let’s see how this chef operates:

from transformers import VitsModel, AutoTokenizer
import torch

# Load model and tokenizer
model = VitsModel.from_pretrained("facebook/mms-tts-hau")
tokenizer = AutoTokenizer.from_pretrained("facebook/mms-tts-hau")

# Prepare your text input
text = "some example text in the Hausa language"
inputs = tokenizer(text, return_tensors="pt")

# Generate waveform
with torch.no_grad():
    output = model(**inputs).waveform

4. Saving and Playing the Output

Once you have generated the output waveform, you might want to save it as a .wav file or listen to it right away. Here’s how:

import scipy

# Save as .wav file
scipy.io.wavfile.write("techno.wav", rate=model.config.sampling_rate, data=output)

# Play sound in Notebook or Google Colab
from IPython.display import Audio
Audio(output, rate=model.config.sampling_rate)

Troubleshooting

While using the Hausa TTS model, you might encounter some hiccups. Here are a few common issues and their solutions:

• Model Not Found Error: Make sure you’ve typed the model name correctly. Check for typos in the string “facebook/mms-tts-hau”.
• Python Package Import Errors: Ensure that you have installed the transformers and torch libraries properly. You can reinstall them to resolve any issues.
• Invalid Input Text: The model works best with clear text. Avoid special characters unless they are a part of the Hausa lexicon.
