Speech Stream isn't completely understandable.

Context: https://googlecloudplatform.github.io/google-cloud-ruby/#/docs/google-cloud/v0.22.0/google/cloud/speech/project?method=stream-instance

I'm not sure what the correct sending rate is given a sample size of 44100Hz with 16bit rate. I was informed to send 88200 bytes per second, and I also tried brute forcing different values. The error message doesn't help and additional information in the error message would be helpful. Such as, how to better calibrate the transmission rate given a sample rate and encoding. I want to note that I used the data in audio.grpc.content as the payload.

Any help would be appreciated! Thank you.

Error:
11:Audio data is being streamed too fast. Please stream audio data approximately at real time.

Code:

require 'google/cloud/speech'

# Stream to speech and wait for transcription... 
speech = Google::Cloud::Speech.new

# Setup raw file to be sent in as an Asynchronous job maximum time is ~80mins
audio = speech.audio "prince.raw",
                      encoding: :raw, sample_rate: 44100,
                      language: :ja 

# Send stream job
stream = speech.stream encoding: :raw, sample_rate: 44100, language: 'ja'

# Result callback
stream.on_result do |results|
  result = results.first
  puts result.transcript
end

# Error callback
stream.on_error do |error|
  puts error
end

# Start callback
stream.on_speech_start do 
  puts "Started listening"
end

# Complete callback
stream.on_complete do
  puts "Finished"
end

bytes_sent = 0
chunk_size = 88200
bytes_total = audio.grpc.content.size # Content of my raw file (This may be wrong)..

# Send one chunk per second 
while bytes_sent < bytes_total do 
  stream.send audio.grpc.content[bytes_sent, (bytes_sent + chunk_size)]
  bytes_sent += chunk_size 
  sleep 1
end

# Finished sending
stream.complete!

# Stop stream
stream.stop
