How to enable text preprocessing

The enable_preprocessing parameter improves pronunciation of numbers, dates, currencies, and mixed-language text.

It is optional — if omitted, default is False (no preprocessing).

When enabled:

• Numbers are expanded (e.g., "Rs. 1,00,000" → “rupees one lakh”)
• Dates are read naturally (e.g., “25th December, 2024” → “twenty-fifth December two thousand twenty-four”)
• Abbreviations and symbols are handled correctly

Example Code

1
from sarvamai import SarvamAI
2
from sarvamai.play import save

# Initialize the REST client
5
client = SarvamAI(api_subscription_key="YOUR_API_SUBSCRIPTION_KEY")
6
7
# Generate speech using REST
8
audio = client.text_to_speech.convert(
9
    text="Welcome to Sarvam AI!",
10
    model="bulbul:v2",
11
    target_language_code="en-IN",
12
    enable_preprocessing=True  # Enable smart text normalization

)

save(audio, "output1.wav")
