Whisper API integrates via standard REST calls. OpenAI provides SDKs for Python, Node.js, and other languages. The API is straightforward:
python
from openai import OpenAI
client = OpenAI()
audio_file = open(“meeting.mp3”, “rb”)
transcript = client.audio.transcriptions.create(
model=”whisper-1″,
file=audio_file
)
Self-hosting WhisperX involves Docker containers, GPU configuration, and dependency management. Our team spent 4 hours getting WhisperX running with proper speaker diarization.
Otter.ai offers the smoothest integration for meeting tools. Install the Zoom app, authorize Otter, and it auto-joins meetings. The Business tier includes API access for custom integrations.
