Really shines in one specific use case
I've spent a lot of time creating shorter cut-down videos of my live streams and YouTube videos. But with Spoke this goes a lot quicker: Upload a video, highlight the text you want for a social media or cut-down clip, download the video and even get the subtitle file.
The voice recognition rate is fairly high (if you have a clean recording) and the editor is good enough to correct errors of the selected highlights. However, for correcting a long transcript I find HappyScribe's transcription editor far superior to Spoke. In Spoke you only have a player for the moments you selected for the summary - correcting the entire script first (e.g. to get a complete transcript) is very tedious, because you can't jump to the current moment in the uncut video or listen to the video as you type.
I really hope Spoke will think about an interface that will make it easier to jump through the video while correcting the uncut transcript. But you could argue that this is not their use case.
Their real strong point is creating summaries - and the functionalities and the interface are perfectly optimized towards this purpose.
Verdict: For quick "video editing" and creating text summaries get Spoke. For complete, long transcriptions have a look at HappyScribe.
