Google Text to Speech: Encountering high latency

[Shalini2]

Hi,

I am using Google Text to Speech client library according to the following code:

gcp_creds = service_account.Credentials.from_service_account_info()

client = texttospeech.TextToSpeechClient(credentials=gcp_creds)

synthesis_input = texttospeech.SynthesisInput(text=text)

if <insert language detecting logic>:

language = "hi-IN"

else:

language = "en-IN"

voice = texttospeech.VoiceSelectionParams(

language_code=language, name=language + "-Standard-D"

)

audio_config = texttospeech.AudioConfig(

audio_encoding=texttospeech.AudioEncoding.LINEAR16,

sample_rate_hertz=RATE,

speaking_rate=0.9,

pitch=0,

effects_profile_id=["telephony-class-application"],

)

res = client.synthesize_speech(

input=synthesis_input, voice=voice, audio_config=audio_config

)

I'm experiencing very high latency, from 500 ms to 22000 ms. I have tried reducing this using different configurations but was unsuccessful. 

How can I reduce latency to below 500 ms?
