    func synthesize(text: String,

                    outputFormat: TTSAudioOutputFormat = .riff16Khz16BitMonoPcm,

                    lang: String = "eastus",

                    gender: TTSGender = .female,

                    callback: @escaping (Data) -> ()) {

        self.authentication.getAccessToken { (accessToken: String) in

            let message = ""

            let encoding = String.Encoding.utf8

            TTSHttpRequest.submit(withUrl: TTSSynthesizer.ttsServiceUri,

                                  andHeaders: [

                                    "Content-Type": "application/ssml+xml",

                                    "X-Microsoft-OutputFormat": outputFormat.rawValue,

                                    "Authorization": "Bearer " + accessToken,

                                    "User-Agent": "TTSiOS",

                                    "content-length": "(message.lengthOfBytes(using: encoding))"

                ],

                                  andBody: message.data(using: encoding)) { (c: TTSHttpRequest.Callback) in

                                    guard let data = c.data else { return }

                                    callback(data)

            }

        

        }

    }

@Bhagwan Rajput@BHAGWAN RAJPUT Welcome to Microsoft Q&A Forum, Thank you for posting your query here! .

You might observe one of several authentication errors, depending on the programming environment, API, or SDK. Here are some example errors:

• Did you set the speech resource key and region values?
• AuthenticationFailure
• HTTP 403 Forbidden or HTTP 401 Unauthorized. Connection requests without a valid Ocp-Apim-Subscription-Key or Authorization header are rejected with a status of 403 or 401.
• ValueError: can't construct SpeechConfig with the given arguments (or a variation of this message). This error could be observed, for example, when you run one of the Speech SDK for Python quickstarts without setting valid credentials.
• Exception with an error code: 0x5. This access denied error could be observed, for example, when you run one of the Speech SDK for C# quickstarts without setting valid credentials.

For baseline authentication troubleshooting tips, see validate your resource key and validate an authorization token.

.

Hope this helps.
