Google Speech Invalid language code
Understanding Google Speech API
Google Speech API is a powerful tool that allows developers to convert audio to text by applying neural network models in an easy-to-use API. It supports over 120 languages and variants, enabling developers to reach a global audience. The API is commonly used in applications that require voice recognition capabilities, such as virtual assistants, transcription services, and voice-controlled devices.
Identifying the Symptom: Invalid Language Code
When using the Google Speech API, you might encounter an error message indicating an 'Invalid language code'. This error typically occurs when the language code specified in the API request does not match any of the supported language codes.
Common Error Message
The error message usually appears as follows:
{
"error": {
"code": 400,
"message": "Invalid language code",
"status": "INVALID_ARGUMENT"
}
}
Understanding the Issue: Invalid Language Code
The 'Invalid language code' error is a result of specifying a language code that is not recognized by the Google Speech API. Each language supported by the API has a specific code, and using an incorrect or unsupported code will trigger this error.
Root Cause
The root cause of this issue is typically a typo in the language code or using a language code that is not supported by the API. It is crucial to ensure that the language code matches one of the valid codes listed in the API documentation.
Steps to Fix the Invalid Language Code Issue
To resolve the 'Invalid language code' error, follow these steps:
Step 1: Verify the Language Code
Check the language code you are using in your API request. Ensure that it matches one of the valid language codes listed in the Google Speech-to-Text API documentation.
Step 2: Update the API Request
If you find that the language code is incorrect, update your API request with the correct code. For example, if you intended to use English (United States), the correct language code is en-US.
Step 3: Test the API Request
After updating the language code, test your API request to ensure that the error is resolved. You can use tools like cURL or Postman to send the request and verify the response.
Conclusion
By ensuring that the language code in your API request is valid and supported, you can effectively resolve the 'Invalid language code' error. Always refer to the official Google Speech-to-Text API documentation for the most up-to-date list of supported languages and their corresponding codes.
