Azure TTS Error 404

Migs Marbella 0

I get error 404 when trying to fetch the mp3 file via fetch. I am using Node.js in the backend.

More details:

I created a functionality in my app that creates an XML document containing all SSML tags as specified by Microsoft Azure. Is it possible some SSML tags generated contain incorrect content that makes it impossible to convert the document into a speech?

Hi @Migs Marbella,

Thank you for reaching out to Microsoft Q&A forum!

A 404 error when fetching the MP3 file from Azure Text-to-Speech (TTS) typically indicates that the requested resource cannot be found. This issue may arise from incorrect SSML content being generated. To resolve this, first, ensure your SSML is well-formed and adheres to Azure's specifications. Inspect the response from the Azure TTS API for any error messages that may provide more context.

Please look into: SSML document structure.

Also, you can try using other supported programming languages might resolve the issue.

I hope this helps! Thank you.

Hi @santoshkc

It is indeed more likely the case. Some requests I've sent had been successful. Thank you for having the time to respond.

Hi @Migs Marbella,

The 404 error could mean there's an issue with the SSML tags you’re using. Double-check that the SSML follows Azure’s guidelines, as small mistakes can cause problems. Try logging both successful and failed requests to spot any patterns, and use an XML validator to catch any syntax errors. You can also test it in Azure’s TTS Studio to see which tags might be causing issues.

Thank you.

Hello @santoshkc

Latest updates: The files are actually being saved in the designated TTS folder as provided by the link created after processing the XML. Why does it keep returning 404 error when it is fetched via axios?

Hi @santoshkc

The created audio files are actually being saved. However, the links provided return the 404 Error code when accessed via 'fetch' and it seems the blob is not available. But when I click the link itself, it opens another tab in my browser and the actual file is automatically played. Is it possible an audio file created has no blob or is it a CORS issue?

Hi @Migs Marbella,

Thank you for your follow-up query.

It’s likely a permissions or CORS issue. Make sure your Azure Blob container allows public access or use an SAS token if it’s private. Also, check CORS settings to allow your app’s domain for GET requests. If using an SAS token, ensure it hasn't expired.
