Add synthesized speech audio tracks to videos.


Developer website: Sinusoid Pty Ltd

VideoSpeak allows you to easily add synthesized speech audio tracks to existing videos and movies. Its simple operation allows a voice-over without the use of a microphone or other audio equipment.

VideoSpeak Features:
  • How many times have you seen a demonstration or instructional video on YouTube which has no subtitles, and no narration. You are just left to guess what they are doing.
  • Have you ever shot a video but then later wanted to add a description?
  • VideoSpeak allows you to quickly narrate a video after you've finished shooting it, using high quality synthesized speech.
  • Because VideoSpeak uses the built-in voices in OS X, there is no time-wasting setup of microphone or audio equipment.
  • The multiple voices available in OS X allows VideoSpeak to easily add a narration with whatever voice you choose, including localized and regional accents.
  • With VideoSpeak you can use different voices for each added speech track. You might want to appear to have two people talking to each other.
  • A completed video with added narration can be ready for export within a few minutes.
  • VideoSpeak is ideal for creating speech tracks on instructional or training videos.
  • Narration could be added to give life to vacation movies.
  • Novelty voices can be used to add interest to funny videos.
  • Using high quality synthesized voices allows standardisation on a single voice for corporate use. Any user can produce a video using the chosen voice, no need for expensive voice-overs each time a new company video is produced
