Speechify TTS

The Speechify TTS provider enables your agent to use Speechify's high-quality text-to-speech models for generating natural-sounding voice output.

Installation

Install the Speechify-enabled VideoSDK Agents package:

pip install "videosdk-plugins-speechify"

Importing

from videosdk.agents.plugins import SpeechifyTTS

Authentication

The Speechify plugin requires an Speechify API key.

Set SPEECHIFY_API_KEY in your .env file.

Example Usage

from videosdk.agents.plugins import SpeechifyTTS
from videosdk.agents import Pipeline

# Initialize the Speechify TTS model
tts = SpeechifyTTS(
    voice_id="kristy",
    model="simba-english"
)

#  Add tts to pipeline
pipeline = Pipeline(tts=tts)

note

When using .env file for credentials, don't pass them as arguments to model instances or context objects. The SDK automatically reads environment variables, so omit api_key and other credential parameters from your code.

Configuration Options

• voice_id: (str) The Speechify voice to use (default: "kristy").
• api_key: (str) Speechify API key. Can also be set via the SPEECHIFY_API_KEY environment variable.
