How I can take to human accent (Wavenet or Ssml voices)? - api

Question

I am using this google cloud text to speech like they write in their website. https://codelabs.developers.google.com/codelabs/cloud-text-speech-csharp/#6 )
But there are no details about how to take output Wavenet voices (Ssml) . This coding output is normal voices.
My question is, with this code, how I can take to human accent (Wavenet or Ssml voieces)?
using Google.Cloud.TextToSpeech.V1;
using System;
using System.IO;
namespace TextToSpeechApiDemo
{
class Program
{
static void Main(string[] args)
{
var client = TextToSpeechClient.Create();
// The input to be synthesized, can be provided as text or SSML.
var input = new SynthesisInput
{
**Text = "This is a demonstration of the Google Cloud Text-to-Speech API"
};
// Build the voice request.
var voiceSelection = new VoiceSelectionParams
{
LanguageCode = "en-US",
SsmlGender = SsmlVoiceGender.Female**
};
// Specify the type of audio file.
var audioConfig = new AudioConfig
{
AudioEncoding = AudioEncoding.Mp3
};
// Perform the text-to-speech request.
var response = client.SynthesizeSpeech(input, voiceSelection, audioConfig);
// Write the response to the output file.
using (var output = File.Create("output.mp3"))
{
response.AudioContent.WriteTo(output);
}
Console.WriteLine("Audio content written to file \"output.mp3\"");
}
}
}

Here you can check the languages and voices supported in text-to-speech API. As described in this tutorial the speech is characterized by three parameters: the language_code, the name and the ssml_gender.
You can employ the following Python code to translate the text "Hello my name is John. How are you?" into English with the accent en-GB-Standard-A
def synthesize_text(text):
"""Synthesizes speech from the input string of text."""
from google.cloud import texttospeech
client = texttospeech.TextToSpeechClient()
input_text = texttospeech.types.SynthesisInput(text=text)
# Note: the voice can also be specified by name.
# Names of voices can be retrieved with client.list_voices().
voice = texttospeech.types.VoiceSelectionParams(
language_code='en-GB',
name='en-GB-Standard-A',
ssml_gender=texttospeech.enums.SsmlVoiceGender.FEMALE)
audio_config = texttospeech.types.AudioConfig(
audio_encoding=texttospeech.enums.AudioEncoding.MP3)
response = client.synthesize_speech(input_text, voice, audio_config)
# The response's audio_content is binary.
with open('output.mp3', 'wb') as out:
out.write(response.audio_content)
print('Audio content written to file "output.mp3"')
text="Hello my name is John. How are you?"
synthesize_text(text)
I am not familiar with C# language but judging by the C# and java documentations you should be able to define the name parameter as well to tune the speech.
