Is there a way to specify the language only, not the voice?

[HubKing]

Sometimes, I only care about that the text is read in the correct language, no matter which voice it is. For example, I just want "Bonjour" to be read in French, no matter which French voice is used. I tried passing fr-FR to the second argument of Communicate(), but that caused Invalid voice error.

Must I specify a specific voice?

Yes, you must specify a specific voice. However you could use the VoiceManager which selects a voice for you. For example,

#!/usr/bin/env python3

import asyncio

import edge_tts
from edge_tts import VoicesManager

TEXT = "Hoy es un buen día."
OUTPUT_FILE = "spanish.mp3"


async def _main() -> None:
    voices = await VoicesManager.create()
    voice = voices.find(Gender="Male", Language="es")
    # Also supports Locales
    # voice = voices.find(Gender="Female", Locale="es-AR")

    communicate = edge_tts.Communicate(TEXT, voice[0]["Name"])
    await communicate.save(OUTPUT_FILE)


if __name__ == "__main__":
    loop = asyncio.get_event_loop()
    try:
        loop.run_until_complete(_main())
    finally:
        loop.close()
