OpenAI Speech to Text Configuration

OpenAI STT Configuration Interface The OpenAI STT configuration screen in PipesHub where you’ll enter your API Key and Model Name PipesHub integrates with OpenAI’s speech-to-text models to enable voice input in AI workflows and agents. Once configured, PipesHub can transcribe spoken audio into text using OpenAI’s Whisper and GPT-4o transcription models.

​
Required Fields

​
API Key *

The API Key is required to authenticate your requests to OpenAI’s transcription services. How to obtain an API Key:
  1. Log in to your OpenAI account
  2. Navigate to the API Keys section
  3. Create a new secret key
  4. Copy the key immediately (it will only be shown once)
Security Note: Your API key should be kept secure and never shared publicly. PipesHub securely stores your API key and uses it only for authenticating requests to OpenAI.

​
Model Name *

The Model Name field defines which OpenAI transcription model you want to use. Available OpenAI STT models:
  • whisper-1 — OpenAI’s Whisper model, supports 50+ languages
  • gpt-4o-transcribe — GPT-4o powered transcription, highest accuracy
  • gpt-4o-mini-transcribe — GPT-4o Mini powered transcription, faster and more cost-effective
How to choose a model:
  • For broad language support and general-purpose transcription, use whisper-1
  • For the highest transcription accuracy, use gpt-4o-transcribe
  • For a balance of speed and accuracy at lower cost, use gpt-4o-mini-transcribe
  • Check OpenAI’s speech-to-text documentation for the most up-to-date model options

​
Optional Fields

​
Model Friendly Name

A human-readable label for this configuration, shown in the PipesHub UI instead of the raw model name. Useful when you have multiple configurations of the same provider.

​
Configuration Steps

As shown in the image above:
  1. Click Configure on the OpenAI provider card in the STT tab
  2. Enter your OpenAI API Key in the designated field (marked with *)
  3. Enter the Model Name (marked with *), for example whisper-1
  4. (Optional) Set a Model Friendly Name
  5. Click Add Model to save and validate your credentials
Both the API Key and Model Name are required fields to successfully configure OpenAI STT integration.

​
Usage Considerations

  • Each transcription request counts against your OpenAI API quota and billing
  • whisper-1 is priced per minute of audio transcribed
  • GPT-4o transcription models may be priced differently — check OpenAI’s pricing page
  • Audio files are sent to OpenAI’s API servers for processing

​
Troubleshooting

  • If you encounter authentication errors, verify your API key is correct and has not expired
  • Ensure your OpenAI account has billing enabled
  • Check that the model name is spelled exactly as shown (e.g. whisper-1, not Whisper-1)
  • Verify your account has access to the audio transcription API
