Afro-TTS

Afro-TTS is the first pan-African accented English speech synthesis system capable of generating speech in 86 African accents. It includes 1000 personas representing the rich phonological diversity across the continent for applications in Education, Public Health, and Automated Content Creation. Afro-TTS lets you clone voices into different African accents by using just a quick 6-second audio clip. The model was adapted from the XTTS model which was developed by Coqui Studio.

Features

Supports 86 unique African accents
Voice cloning with just a 6-second audio clip
Emotion and style transfer by cloning
Multi-accent English speech generation
24kHz sampling rate for high-quality audio

Performance

Afro-TTS achieves near ground truth Mean Opinion Scores (MOS) for naturalness and accentedness. Objective and subjective evaluations demonstrated that the model generates natural-sounding accented speech, bridging the current gap in the representation of African voices in speech synthesis.

Languages

Afro-TTS supports only English languages for now. Stay tuned as we continue to add support for more languages. If you have any language requests, feel free to reach out!

Using Afro-TTS:

Install the Coqui TTS package:

pip install TTS

Run the following code:

python

from scipy.io.wavfile import write
from TTS.tts.configs.xtts_config import XttsConfig
from TTS.tts.models.xtts import Xtts

config = XttsConfig()
config.load_json("intronhealth/afro-tts/config.json")
model = Xtts.init_from_config(config)
model.load_checkpoint(config, checkpoint_dir="intronhealth/afro-tts/", eval=True)
model.cuda()

outputs = model.synthesize(
    "Abraham said today is a good day to sound like an African.",
    config,
    speaker_wav="audios/reference_accent.wav",
    gpt_cond_len=3,
    language="en",
)

write("audios/output.wav", 24000, outputs['wav'])
