When I try to use the Python example, but replace api_key with my own from the portal, I am able to successfully get a token; however, I get a 401 when I call "westus.tts.speech.microsoft.com"

headers = {"Ocp-Apim-Subscription-Key": api_key}

The best practice is to have finally block to check status of the connection and close it.

`//webRequest.disconnect();

        this.accessToken = strBuffer.toString();

    }catch (Exception e){
        Log.e(LOG_TAG, "Exception error", e);
    }
    finally {
        if (webRequest != null) {
            webRequest.disconnect();
        }
    }`

I've got a PowerShell script I used to demo Cognitive TTS for a User Group. Any place I can upload for the Community consume?

what‘s the different between android and Samples-Http/Android

I'm trying to use the Cognitive Services text-to-speech API, but no matter what I try, I get a 401 Unauthorized response.

I've created a Cognitive Services resource on my subscription in the West Europe region. Type is All Cognitive Services, status is active. I downloaded the CSharp sample and entered the west europe URLs and my cognitive services subscription key into the code. When I run the sample, the access token is retrieved just fine, but the text-to-speech request returns 401.

Token URL: https://westeurope.api.cognitive.microsoft.com/sts/v1.0/issueToken
Service URL: https://westeurope.tts.speech.microsoft.com/cognitiveservices/v1

I've checked that the URLs are correct, I'm using the same region in both and the same one as the created resource. I went throught the troubleshooting page (https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/troubleshooting) and got the same 401 issue. I tried running the TTS request from Postman. I've tried both Key1 and Key2 from the portal, and tried to regenerate a key.

I've decoded the access token and it seems like it has pretty much the right stuff in it, as far as I can tell. The only weird thing is, the exp field is a string and not a number (incorrect for a JWT). Could that be a bug in the auth system that is causing this error or am I doing something wrong?

I have created an ASP .Net MVC App and I implemented C# TTS example to my application. TTS working fine when my application running on the local machine. But after deploying applications on Azure environment It's stopped working. Can anybody help me to find the solution. Any other way to implement TTS in ASP .NET MVC App.

Hi,

We are trying this with MS BOT Builder.

Can you help how can we send "_data" (Wave date) to user as File where he can play it. ?

I have integrated your TTSClient.cs in my mvc project, in localhost it works fine. But i have hosted in our server IIS and generated https:// public url in that text-to-speech is not working.
Is need to generate app id and client id unique for my application ? if so and how do get that ?
please suggest me on this...

Hey , I am getting 2 types of errors.

1. Illegal instruction : 4
2. null < Buffer >

There is no references to these errors. Can you guys help me ?
I am using the example file included in the project

Hi. I am using Java to call TTSService.Synthesize. For some reason takes a long time for the service to come back with the MP3. What AudioOutputFormat should I use to make the smallest mp3 and hopefully stream it to the client?

Thanks.

i need to know when the audio is done playing

my gosh。only java simple works

Hi!

Congratulation, but I have one questions.

How do I know when the Synthesizer is finished? For example, when the Synthesizer finish, I change to other app,

It needs to know when Synthesizer is DONE/FINISHED to run another things.

Thanks

i think it would be best experience?

I would like to integrate Azure TTS into my project but I can run sample project only with demo API key. When using this sdk into real project with subscribed API key, the API always return 403. I dived deep into sdk project and see these values, so where is it from and how to get them?

In the code you are using: GenerateSsml(inputOptions.Locale, genderValue, inputOptions.VoiceName, inputOptions.Text) to generate the SSML.
How can we add SSML tags to change the voice output via SSML, like speaking rate, pronunciation etc?
Thanks

How can I change speech rate. I have seen this https://docs.microsoft.com/en-us/azure/cognitive-services/speech/api-reference-rest/bingvoiceoutput but how to use this should be like this
"<speak version='1.0' xml:lang='ja-JP'><voice xml:lang='ja-JP' xml:gender='Female' rate='+30.00%' name='Microsoft Server Speech Text to Speech Voice (ja-JP, Ayumi, Apollo)'>some text</voice></speak>" ?

It used to work fine a month ago, but I ran the same program and get error today.

I've tried:

1. Create new keys to test if it works.

2. Use Node.js and C# example.

I still get error messages running examples

There is "List keys" in Azure activity log every time I run my program.

It looks like any key I created is now invalid.

C# sample error message:

Node.js sample error message:

(Note that I am using new created keys and still get this message.)

There won't be any problem for anyone who really want to integrate TTS,but it would be more convenient for iOS developer.

Amazon Polly FAQ says that you are allowed unlimited re-use.

Q. Can I use the service for generating static voice prompts that will be replayed multiple times?
Yes, you can. The service does not restrict this and there are no additional costs for doing so.

I can't find a similar clause for the Bing TTS offering. For my own commercial use, I expect it's allowed.

However, I would like to generate prompts for FreeSWITCH and distribute it (general project is under MPL 1.1) and I'm sure we should have an official notice of what license, if any, covers the the generated audio files.

Thanks!

Dear sirs,

I´am trying to use Bing Speech library service to translate speech to text in my ChatBot, but this error happens in method "RecognizeAsync" of class "SpeechClient".

Could not load file or assembly Bond.IO, Version=1.0.0.0, ... or one of its dependencies. The located assembly manifest definition does not match the assembly reference.

All nuget packages are up to date, as is my Visual Studio 2017 Enterprise.

Thank you for any help.

TTS Example works fine in emulator but not able to play the audio from webchat when deployed in azure.

Where is the audo file stored when execute Speak? # #

i need to do TTS in client side, so is there any source/sample available ?
could someone please help on this.

I have a asp mvc project using text to speech api. This project work for a year without problems.
A few days ago I've noticed that this project stop generating audios. I don't know when exactly this happened.
The api is returning wav audios that I can't play, the file throw an error when I try to play it.
Was there any significant change that I have to make in my project to get this working again?

Most samples could be updated.

All of the end points, including this shown in the sample https://westus.tts.speech.microsoft.com/cognitiveservices/v1, return 404. Have these changed?

After filling in the API-key required by the Python TTS I acquire the access token, however the POST request that follows outputs a 403 forbidden.

Resolution:
in Synthesizer.java
change
String ssml = "<speak version='1.0' xml:lang='" + m_serviceVoice.lang + "'><voice xml:gender='" + m_serviceVoice.gender + "'";
to
String ssml = "<speak version='1.0' xml:lang='" + m_serviceVoice.lang + "'><voice xml:lang='" + m_serviceVoice.lang + "' xml:gender='" + m_serviceVoice.gender + "'";

API Reference:
<speak version='1.0' xml:lang='en-US'><voice xml:lang='en-US' xml:gender='Female' name='Microsoft Server Speech Text to Speech Voice (en-US, ZiraRUS)'>Microsoft Bing Voice Output API</voice></speak>

According to LeakCanary, this is consistently causing the Activity passed in SpeechRecognitionServiceFactory.createMicrophoneClient() to be leaked.

I am behind a proxy and I get the error [WinError 10060]. Where do I put my proxy settings in the code.?

after running the python code there is no voice heard and no errors

give me the error
Error: Error executing POST request！

Copied from original issue: microsoft/ProjectOxford-ClientSDK#4

Hi what is the general rule of thumb for the confidence in Microsoft Cognitive Services? Do you have any graph or anything available which states if it is less than 50% don't trust the results and if it is above 50% do trust the results. Like also if it is 90%+ it is extremely accurate results etc.

When I make a http request to https://speech.platform.bing.com/synthesize, the server response 204 with error message 'Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:58231' is therefore not allowed access.' How can i solve this problem?

Here post_speak_data.length is actually not the right way to get the Content-Length, because NodeJS has native support for UTF-8. So "你好".length == 2 while the correct way of calculating Content-Length should be by bytes rather than characters.

Here is the correct way to calculate byte size: Buffer.byteLength(post_speak_data, 'utf-8')

This is my current code, what I want the program to say is passed through Socket.io connection, but the program stopped working after spoken first sentence, and I have no clue what caused the program to stop.
