Trouble with JavaScript sample in Text-to-speech quickstart - function doesn't return anything

mkb13 11

I am writing a Blazor app that uses TTS and am forced to use the JavaScript API unfortunately due to the problem mentioned here: https://github.com/Azure-Samples/cognitive-services-speech-sdk/issues/930.

I am following the examples in the quickstart here: https://learn.microsoft.com/en-us/azure/cognitive-services/speech-service/get-started-text-to-speech?tabs=script%2Cwindowsinstall&pivots=programming-language-javascript -- specifically the first snippet under "Get result as an in-memory stream".

function synthesizeSpeech() {  
    const speechConfig = sdk.SpeechConfig.fromSubscription("

Could you please try this sample repo directly? https://github.com/Azure-Samples/cognitive-services-speech-sdk/tree/master/quickstart/javascript/node/text-to-speech

There maybe something wrong when trying to reorganize your code from the quick-start-doc. Please check the sample repo and have a try.

Thanks but the sample (both the node.js version and the browser version) does not use the code path I'm talking about. The sample writes the output to a file -- it doesn't purport to return anything from the first callback.

I'm trying to use the "Get result as an in-memory stream" example in the quick-start and get the output as a stream or byte array. I don't think it works for me to put it in a file because I'm running this in a browser and want to receive the contents in memory.

Let me know if I'm looking at the wrong sample and if there's another one that returns the data produced by speakTextAsync.

Also note that in the C# API this is extremely easy and straightforward. I just can't use C# due to the issue mentioned in https://github.com/Azure-Samples/cognitive-services-speech-sdk/issues/930 . It would be great if that were fixed!

Same issue, more than a year later. I've spent 2 days trying to figure out how to use Microsoft's Cognitive Services in Microsoft's flagship Web technology.

Seems like that should be a thing that they'd encourage-- I dunno, with an easy way to do it.
