OpenAI STT

The OpenAI STT provider enables your agent to use OpenAI's speech-to-text models (like Whisper) for converting audio input to text.

Installation

Install the OpenAI-enabled VideoSDK Agents package:

pip install "videosdk-plugins-openai"

Importing

from videosdk.plugins.openai import OpenAISTT

Example Usage

from videosdk.plugins.openai import OpenAISTT
from videosdk.agents import CascadingPipeline

# Initialize the OpenAI STT model
stt = OpenAISTT(
    # When OPENAI_API_KEY is set in .env - DON'T pass api_key parameter
    api_key="your-openai-api-key",
    model="whisper-1",
    language="en",
    prompt="Transcribe this audio with proper punctuation and formatting."
)

#  Add stt to cascading pipeline
pipeline = CascadingPipeline(stt=stt)

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, videosdk_auth, and other credential parameters from your code.
