Proof of Concept for transcoding podcasts into text using GCP Speech2Text service, following its NODE JS tutorial.

Installation

1. Download this repo:

git clone https://github.com/emibcn/Podcast2Text.git

2. Change directory into it:

cd Podcast2Text

3. Create local directories:

mkdir flac credentials

4. Create GCP credentials for consuming Speech2Text service at GCP IAM with -at least- Service Usage Consumer permission.
5. Copy credentials file to ./credentials directory
6. Create .env file with GOOGLE_APPLICATION_CREDENTIALS=[CREDENTIALS FILENAME] (without directory)

Usage

There is a script helper to transcode any audio file into text. It's syntax is:

./transcode.sh <FILEPATH> [START]

• FILEPATH: Path (relative or absolute) to podcast audio file
• START: Initial start seek (transcode beginning at this position). Same syntax as FFMPEG -ss option.

This will encode the supplied file to FLAC format into ./flac directory and then use the encoded file to send it to GCP Speech2Text service and get its transcription printed on screen.
