I would like to calculate the time duration for sentences when I convert text to speech in Google Cloud in Python. For example, if I have three sentences converted to audio, I would like to know when the first sentence starts in the audio, the second one, etc.
Example:
text= 'Hello, World. I can speak any language. I would like to help you.'
Hello, World: starts 00:00 ends 00:03
I can speak any language: starts 00:04 ends 00:09
I would like to help you: starts 00:10 ends 00:13
Is there something for that in python? here is the main code:
"""Synthesizes speech from the input string of text or ssml.
Note: ssml must be well-formed according to:
https://www.w3.org/TR/speech-synthesis/
"""
from google.cloud import texttospeech
# Instantiates a client
client = texttospeech.TextToSpeechClient()
# Set the text input to be synthesized
synthesis_input = texttospeech.types.SynthesisInput(text="Hello, World. I can speak any language. I would like to help you.")
# Build the voice request, select the language code ("en-US") and the ssml
# voice gender ("neutral")
voice = texttospeech.types.VoiceSelectionParams(
language_code="en-US", ssml_gender=texttospeech.enums.SsmlVoiceGender.NEUTRAL
)
texttospeech_v1beta1.types.cloud_tts_pb2
# Select the type of audio file you want returned
audio_config = texttospeech.types.AudioConfig(
audio_encoding=texttospeech.enums.AudioEncoding.MP3
)
# Perform the text-to-speech request on the text input with the selected
# voice parameters and audio file type
response = client.synthesize_speech(
input_=synthesis_input, voice=voice, audio_config=audio_config
)
# The response's audio_content is binary.
with open("./output.mp3", "wb") as out:
# Write the response to the output file.
out.write(response.audio_content)
print('Audio content written to file "output.mp3"')
