95301: Transcription language code does not match the Conversational Intelligence Service

This error occurs when the languageCode on your Transcription request does not match the language configured on the Intelligence Service referenced by intelligenceService. Each Intelligence Service supports one transcription language only, and Twilio uses en-US by default if you do not set a language when you create the Service.

• The Transcription request includes a languageCode that is different from the language configured on the referenced Intelligence Service.
• The referenced Intelligence Service was created without an explicit languageCode, so the Service language defaulted to en-US while your Transcription request uses a different language.
• You are trying to use one Intelligence Service for calls in multiple languages. An Intelligence Service supports only one LanguageCode, and you cannot update that value after the Service is created.

• Update the Transcription request so languageCode matches the language configured on the Intelligence Service you pass in intelligenceService.
• If you need a different transcription language, create a new Intelligence Service with the required languageCode and use that Service SID or unique name in intelligenceService.
• Create a separate Intelligence Service for each language you need to transcribe.
