* This example assumes the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Http')
loHttp = CreateObject('Chilkat.Http')

loHttp.Login = "apikey"
loHttp.Password = "my_apikey"
loHttp.BasicAuth = 1

* Use your base URL shown in the credentials web page (below your apikey)
lcMyBaseUrl = "https://api.us-south.text-to-speech.watson.cloud.ibm.com/instances/31941e96-7b89-4d56-8993-9cd8f18ec2d8"

loSbUrl = CreateObject('Chilkat.StringBuilder')
loSbUrl.Append(lcMyBaseUrl)
loSbUrl.Append("/v1/synthesize?accept=ACCEPT_TYPE&voice=CHOSEN_VOICE&text=TEXT_TO_SYNTHESIZE")

* Choose "audio/wav" for the output file type.
lnNumReplaced = loSbUrl.Replace("ACCEPT_TYPE",loHttp.UrlEncode("audio/wav"))
* See the choices for voices at https://cloud.ibm.com/apidocs/text-to-speech#synthesize-audio-get

* Send the GET to synthesize the voice.
* The response file will be contained in bdResponseBody
* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.BinData')
