Google WaveNet Invalid Language Code error when using Google WaveNet API.

The language code specified is incorrect or not supported by the API.

Understanding Google WaveNet

Google WaveNet is a powerful text-to-speech (TTS) technology developed by DeepMind, a subsidiary of Alphabet. It is designed to generate human-like speech by using deep neural networks. The tool is widely used in various applications to convert text into natural-sounding speech, enhancing user interaction and accessibility.

Identifying the Symptom

When using the Google WaveNet API, you might encounter an error message stating Invalid Language Code. This error typically occurs when the API request includes a language code that is not recognized or supported by the service.

Common Error Message

The error message might look like this: {"error": {"code": 400, "message": "Invalid Language Code", "status": "INVALID_ARGUMENT"}}.

Exploring the Issue

The Invalid Language Code error arises when the language code provided in the API request does not match any of the supported language codes by Google WaveNet. This could be due to a typo, an outdated code, or using a language that is not yet supported.

Supported Language Codes

Google WaveNet supports a variety of language codes. It is crucial to ensure that the language code you are using is listed in the official documentation.

Steps to Fix the Issue

To resolve the Invalid Language Code error, follow these steps:

1. Verify the Language Code

Check the language code in your API request. Ensure it matches one of the supported codes listed in the Google Cloud Text-to-Speech documentation.

2. Update Your API Request

If the language code is incorrect, update your API request with the correct code. For example, if you intended to use English (US), ensure your request includes "languageCode": "en-US".

3. Test the API Request

After updating the language code, test your API request to ensure the error is resolved. You can use tools like cURL or Postman to send the request and verify the response.

Conclusion

By following these steps, you should be able to resolve the Invalid Language Code error in Google WaveNet. Always refer to the latest documentation for supported languages and codes to prevent similar issues in the future.
