Model name: fa-ir-tts-piper-en-mantatts-v1
Previous name: kiarashQ/fa_IR-mantatts
Sampling rate: 22,050 Hz
Base checkpoint:
ar/ar_JO/kareem/medium/epoch=5079-step=1682020.ckpt (Piper AR, medium)

  --config config.json \
  --text "سلام! حال شما چطور است؟" \
  --output_file out.wav

Python:

import subprocess

text = "سلام! امروز هوا چطور است؟"
subprocess.run([

    "--text", text, "--output_file", "out.wav"
])

🔍 Observations

• The Arabic-base version sometimes pronounces Persian words more correctly than the EN-base model.
• Slightly lower overall accent naturalness compared to EN-base.
• Useful as a complementary voice to EN-base.
