Replay

Replay command

The replay command allows you to replay previously recorded conversations with your Voiceflow project. This is useful for testing changes to your project with consistent inputs, demonstrating flows, or debugging issues.

Usage

voiceflow dialog replay -f RECORD_FILE [options]

Options

Examples

Replay a recorded conversation

voiceflow dialog replay -f my-conversation.json

This will replay all interactions from the recording file against your Voiceflow project.

Replay with a specific user ID

voiceflow dialog replay -f my-conversation.json --user-id user123

This allows you to maintain consistent user state or test with specific user profiles.

Replay in production environment

voiceflow dialog replay -f my-conversation.json -e production

Replays the conversation using your production environment settings.

How replay works

The replay command:

1. Reads the recorded conversation file specified with -f
2. Processes each interaction in sequence, automatically sending user inputs to the Voiceflow API
3. Displays the responses from your Voiceflow project for each interaction
4. Adds brief pauses between interactions to simulate natural conversation timing

Creating recording files

To create a file for replay, use the dialog start command with the --record-file option:

voiceflow dialog start --record-file my-conversation.json

During the conversation, every interaction will be saved to the specified file. When you finish the conversation (by typing exit or pressing Ctrl+C), the complete recording will be available for replay.

Troubleshooting

If the replay produces different results than the original conversation:

1. Check if your Voiceflow project has been modified since the recording
2. Verify you're using the same environment that was used during recording
3. Consider using a consistent user ID if your project relies on user-specific state
4. Ensure any external APIs or services your project depends on are available
