Step 3: Audio file specs. One other limitation is that the API does not support stereo audio files. So the user needs to convert a stereo file to mono file before using the API. In addition, the user has to provide the audio frame rate for the file. The code below helps you figure it out for any ‘.wav' audio file. .NEW. Convert audio to text with automatic transcription If you have clear audio/video recordings in one of these languages: English, French, German, Hebrew, Hindi, Italian, Portuguese, Spanish? Our state-of-the-art machine transcription converts your audio to text in minutes, with close to 90% accuracy. Transcribing Audio with Google Docs Voice Typing It may come as news to you, but you can indeed transcribe audio or video with Google Docs' Voice Typing feature. The tool converts speech into text, and can be handy if you find dictation faster than typing, or if you need to transcribe either live or videoconference meetings. This tutorial will walk through using Google Cloud Speech API to transcribe a large audio file. All code and sample files can be found in speech-to-text GitHub repo. Transcribe large audio files using Python & our Cloud Speech API.

Give your bucket a unique name, choose a location which suits your needs and leave the other default values. Click then on Create.

You will get redirected to your new bucket. Under Overview, there is a field called Link to gsutil. That information will be later used to access your bucket from the command line.

Google's speech-to-text API works with .flac audio files. In my case, I had .mov and .ogg files. I used FFmpeg to convert my audio files to .flac.

I used homebrew to install ffmpeg:

This will take a while, so be patient.

Once ffmpeg is installed, you can convert your audio files to .flac via:

The output is quite verbose, so I skipped it here.

Transcribing Short Audio Files (<1 min)

Small audio files with content less than one minute can be transcribed without uploading them to a gcloud bucket. From within the same directory where your .flac file lies, run:

See https://cloud.google.com/speech/docs/languages for a list of the currently supported language codes.

How To Transcribe Audio File To Text

In my case this was an audio file which I recorded myself with the Quicktime Player on my MBP. The transcription had only one mistake: 'wie gut diese ist Google ..' should have been 'wie gut dieses Google ..'. I also had a longer break before the last 'alternatives' sequence, so I guess that's why google split it up.

After converting the .mov file to .flac and running the gcloud ml command, I first got the following error:

I fixed this by converting the .flac from stereo to mono and using the newly resulting file:

For more information have a look at https://trac.ffmpeg.org/wiki/AudioChannelManipulation.

Long audio files will be transcribed via Asynchronous speech recognition. First, convert your audio file to .flac as described above (I had to convert my large file to mono again, as explained under Troubleshooting). In a next step, upload your file to the storage bucket created earlier:

Make sure to replace poehlmann with your bucket name. Once it is done, you can check your bucket in your browser:

You are now ready to transcribe the audio file by running

You can poll the operation until it completes by running

Or use describe instead of wait if you only want to request a status update without polling.

Make sure to replace the operation ID with yours.

Transcribe

Once the operation is done the above describe command will return the transcribed data as .json data like in the above example of short audio files.

My actual goal was to use Google's speech-to-text API for transcribing lectures which I recorded with my MBP. It turned out the quality of those audio files is not good enough for the API and resulted in garbage transcriptions, even though it is mostly easily understandable when listening to the audio as a human. My best guess is one needs audio files recorded with a microphone in order to achieve some nice results.

Transcribing an English audio message from a frend sent over Telegram gave ok-ish results. The message was a bit technical (about computer processors, RAM etc.) and some of the technical words were not understood by the API. However, since that friend of mine is not a native English speaker I'm not sure if the API is just a bit weak with technical words or rather with non-native speakers.
