Use the same voice ID in code
The preset name is the same in the open source Kokoro tools. With MLX-Audio on Apple Silicon:
mlx_audio.tts.generate --model mlx-community/Kokoro-82M-bf16 \
--text "Hello from Kokoro." --voice af_sky --lang_code aWith the kokoro Python package:
from kokoro import KPipeline
pipeline = KPipeline(lang_code="a")
for _, _, audio in pipeline("Hello from Kokoro.", voice="af_sky"):
...The first letter of the ID sets the accent (a American, b British) and the second sets the speaker (f female, m male). The language code must match.
