Auphonic has been well known in the podcasting field because of its great tool that makes audio editing and podcast cleanup a breeze. But unknown to some, Auphonic has a ton of features that’s not limited to audio cleanup or post production processing but some other bells and whistles that some of you are probably paying $1/per minute.

One of its great features you should test out is Auphonic Speech Recognition. If you want to automate your podcast transcription and turn your audio/video files into text transcripts, then this speech recognition feature from Auphonic is something you might be interested in.

How does Auphonic Speech Recognition Work?

Auphonic’s speech recognition feature harnesses the power of speech recognition services like Google Speech API and You will have to add either of these automatic speech recognition services into your Auphonic’s “External Services”

Google Speech API

Google’s Speech API can be accessed by signing up to Google’s Cloud Platform. There’s also a 365-day free trial (yes, it’s a whole year) plus an additional $300 credits.

Transcription Quality

Based on the tests that I’ve done, the transcription can be really great, but there are some if’s to that:

You can really achieve great quality if:

  1. Your audio quality is great, which means, the words were spoken clearly and with neutral or no heavy accent.
  2. There’s no/minimal background noise
  3. Add word and phrase hints
  4. Add additional words to the vocabulary of the recognition task
  5. Choose the correct language variety, for example, English-US is different from English-UK or English-AU

You can also do some further check by going to Google Cloud Speech API Documentation.
