SpeechBoard is a new "coming soon" Web tool to edit your podcast audio by cutting up the text transcripts. Craig Cannon and Ramon Recuero posted a demo and briefly explain the project in this Medium post:
SpeechBoard… will transcribe your podcasts and allow you to cut anything from the audio by deleting the text from the transcript….You can import your cuts into Adobe Audition or Audacity to fine-tune the edit.
