Install voiceai-sdk on PyPI and call text to speech, speech to text, and streaming with sync or async clients.
voiceai-sdk is the official Python client for the SLNG API. It targets Python
3.9+ and ships a synchronous Slng client and an AsyncSlng for asyncio code.
pip install voiceai-sdk
uv:
uv add voiceai-sdk
from voiceai_sdk import Slng
client = Slng() # reads SLNG_API_KEY
client = Slng(api_key="slng_cu_...") # or pass it explicitly
from voiceai_sdk import Slng
client = Slng()
audio = client.text_to_speech.create(
model_variant="slng/deepgram/aura:2-en",
text="Hello from sunny Barcelona!",
voice="aura-2-thalia-en",
)
audio.write_to_file("hello.wav")
from pathlib import Path
from voiceai_sdk import Slng
client = Slng()
transcript = client.speech_to_text.create(
model_variant="slng/deepgram/nova:3-en",
audio=Path("meeting.wav"),
)
print(transcript.text)
Slng for AsyncSlng:
import asyncio
from pathlib import Path
from voiceai_sdk import AsyncSlng
async def main():
client = AsyncSlng()
transcript = await client.speech_to_text.create(
model_variant="slng/deepgram/nova:3-en",
audio=Path("meeting.wav"),
)
print(transcript.text)
asyncio.run(main())
models = client.models.list()
voices = client.voices.list(model="slng/deepgram/aura:2-en")
