Are you able to post the code to your flow?

Try changing the from language to fr instead of fr-FR and see if that makes any difference.

This gives me another error : _"SST is cancelled with Canceled"_

With a wav file it works but it doesn't help when going with a payload.

Have you tried to use by passing a text file into it? Just passing a string should work.

A string or file works for the ms-text-to-speech node but the errors come from the ms-speech-to-text and it only takes in payload ArrayBuffer or Buffer(NodeJS) class, or with a wav file but no text.  
I think the problem is the buffer class, but I can't figure out why.

One thing to try is use a read file node to read a file you have and then pass that as a buffer.  
It could be just the way the buffer is being passed that is causing the issue.

I just tried it with "a single Buffer object" output, it works, a node debug returns this: msg.payload: buffer[323012]  
With a "Stream of buffer" the message is cut.

There is not too much on what payload types are accepted. Looking within the code it does a check to see if an ArrayBuffer or Buffer(NodeJS). So I would say it only supports a buffer and not a stream buffer, might explain why it is being cut off.

Below is the text:  
msg.payload must be an instance of either ArrayBuffer or Buffer(NodeJS) class

I already got an error message saying that, but the output of the ms-text-to-speech node is a buffer and I can listen to it with an audio play node.  
I'll try to save the buffer in wave format and input it like that to see if it works.

I found a solution, thanks to the node ffmpeg conversion of the node-red-contrib-media-utils palette, no more errors, and it works well.

```auto
