saytime
Saytime generates an audio file from provided text using the macOS say
command.
In addition, it provides the timestamp and duration for each spoken sentence along with the text of each sentence.
That allows the output to be used for synchronized playback testing and video subtitle rendering verification.
Compatibility
saytime requires:
- macOS with
say
- Node 6+
- ffmpeg (providing the
ffmpeg
andffprobe
commands)
