Usage

Configuration

from typecast import Typecast

# Using environment variable (recommended)
# export TYPECAST_API_KEY="your-api-key"
client = Typecast()

# Or pass directly
client = Typecast(
    api_key="your-api-key",
    host="https://api.typecast.ai"  # optional
)

Text to Speech

Basic Usage

from typecast.models import TTSRequest

response = client.text_to_speech(TTSRequest(
    text="Hello, world!",
    voice_id="tc_672c5f5ce59fac2a48faeaee",
    model="ssfm-v30"
))

With Audio Options

from typecast.models import TTSRequest, Output

response = client.text_to_speech(TTSRequest(
    text="Hello, world!",
    voice_id="tc_672c5f5ce59fac2a48faeaee",
    model="ssfm-v30",
    language="eng",
    output=Output(
        volume=120,        # 0-200 (default: 100)
        audio_pitch=2,     # -12 to +12 semitones
        audio_tempo=1.2,   # 0.5x to 2.0x
        audio_format="mp3" # "wav" or "mp3"
    ),
    seed=42  # for reproducible results
))

Voice Discovery

from typecast.models import VoicesV2Filter, TTSModel, GenderEnum, AgeEnum

# Get all voices (V2 API - recommended)
voices = client.voices_v2()

# Filter by criteria
filtered = client.voices_v2(VoicesV2Filter(
    model=TTSModel.SSFM_V30,
    gender=GenderEnum.FEMALE,
    age=AgeEnum.YOUNG_ADULT
))

# Display voice info
print(f"Name: {voices[0].voice_name}")
print(f"Gender: {voices[0].gender}, Age: {voices[0].age}")
print(f"Models: {', '.join(m.version.value for m in voices[0].models)}")

Emotion Control

ssfm-v21: Basic Emotion

from typecast.models import TTSRequest, Prompt

response = client.text_to_speech(TTSRequest(
    text="I'm so excited!",
    voice_id="tc_62a8975e695ad26f7fb514d1",
    model="ssfm-v21",
    prompt=Prompt(
        emotion_preset="happy",  # normal, happy, sad, angry
        emotion_intensity=1.5    # 0.0 to 2.0
    )
))

ssfm-v30: Preset Mode

from typecast.models import TTSRequest, PresetPrompt, TTSModel

response = client.text_to_speech(TTSRequest(
    text="I'm so excited!",
    voice_id="tc_672c5f5ce59fac2a48faeaee",
    model=TTSModel.SSFM_V30,
    prompt=PresetPrompt(
        emotion_type="preset",
        emotion_preset="happy",  # normal, happy, sad, angry, whisper, toneup, tonedown
        emotion_intensity=1.5
    )
))

ssfm-v30: Smart Mode (Context-Aware)

from typecast.models import TTSRequest, SmartPrompt, TTSModel

response = client.text_to_speech(TTSRequest(
    text="Everything is perfect.",
    voice_id="tc_672c5f5ce59fac2a48faeaee",
    model=TTSModel.SSFM_V30,
    prompt=SmartPrompt(
        emotion_type="smart",
        previous_text="I just got the best news!",
        next_text="I can't wait to celebrate!"
    )
))

Async Client

import asyncio
from typecast import AsyncTypecast
from typecast.models import TTSRequest

async def main():
    async with AsyncTypecast(api_key="YOUR_API_KEY") as client:
        response = await client.text_to_speech(TTSRequest(
            text="Hello from async!",
            model="ssfm-v30",
            voice_id="tc_672c5f5ce59fac2a48faeaee"
        ))

        with open("output.wav", "wb") as f:
            f.write(response.audio_data)

asyncio.run(main())
