Speech engine answered ${response.status} ${response.statusT

Error message

Speech engine answered ${response.status} ${response.statusText} for /${engineRequest.endpoint}${suffix}

What it means

The engine responded with a non-success HTTP status for the requested endpoint; the message carries the status, statusText, and endpoint path so the failure is attributable to a specific engine route (e.g. /audio_query or /synthesis). It fires after fetch when the response is not OK, surfacing upstream rejection (bad voice id, engine error, missing speaker) to the provider layer.

Solutions

1. Check the engine logs for the endpoint and status reported in the message
2. Verify the voice/speaker id exists on the engine (400 usually means unknown speaker or style)
3. Ensure query parameters like text are within engine limits; 429/5xx warrant retry after backoff
