Convert speech to text with OpenAI

Speech to text turns an inbound voice note into a text custom field. Use the transcript for Conditions, AI Agents, or human review.

Prerequisites

Collect the audio

In a Flow, use Get User Data / User Input to capture the voice message into a custom field.

Add the OpenAI action

Choose Convert speech to text. Set the audio input to that custom field.

Save the transcript

Write the text output to another custom field (for example voice_transcript).

Use the transcript

Send it back with a Message block, pass it to an AI Agent / AI Action, or Condition on keywords.

Goal	Next step after transcript
Confirm understanding	Echo: “I heard: . Is that right?”
Open-ended support	Send transcript into an AI Agent
Structured routing	Condition / AI Action classify → Go to Flow
Accessibility	Always offer typed input as an alternative

If audio quality is poor, ask the contact to re-record or type. Do not silently guess.
