Also, it is convenient for us to translate our videos from Finnish to English (and vice versa) and add voice overs for our videos. We don’t have to spend so much time in finding the professional voice overs anymore.
"I love this product. I used other similar software before but they didn't work so accurately with the translation. For Hei, I can see that the translation and voiceover work better. We use mainly for our social videos and product tutorials for our videos and client projects."
"Love the tool. They do really well with Spanish and English. I haven't tried other language sets but it works super well with Spanish and English. Use for our product onboarding videos."
"Helped us generate captions for 200+ videos for us so far. Save me tons of time."
Save us so much time in creating voiceover for the Finnish and Vietnamese markets.
