Microsoft Azure Speech is a powerful tool that belongs to the Voice AI API category. It is designed to convert text into natural-sounding speech, enabling applications to communicate with users in a more human-like manner. This tool is widely used in various applications, from virtual assistants to accessibility features, providing a seamless interaction experience.
When using Microsoft Azure Speech, you might encounter the error 'InvalidTextInput'. This error typically manifests when the input text for speech synthesis is not processed correctly, leading to a failure in generating the desired audio output. Users might see error messages or logs indicating that the input text is invalid or unsupported.
The 'InvalidTextInput' error occurs when the text provided to the Azure Speech API contains characters or formats that are not supported by the service. This could include special characters, unsupported languages, or incorrect formatting that the API cannot interpret. Understanding the root cause is crucial for resolving this issue effectively.
To resolve the 'InvalidTextInput' error, follow these actionable steps:
Ensure that your text input does not contain any unsupported characters or formats. You can use online tools or scripts to clean and validate your text. For example, remove any special characters that are not part of the language you are using.
Verify that your text is encoded correctly. UTF-8 is the recommended encoding format for text inputs in Azure Speech. You can convert your text to UTF-8 using various programming languages or text editors.
Ensure that the language of your text input is supported by Azure Speech. You can refer to the Azure Speech Language Support page for a list of supported languages.
Before deploying your application, test the speech synthesis with sample text inputs to ensure that they are processed correctly. This can help identify any issues early in the development process.
