Hello,
Being a teacher my top priority is to provide best edu contents to my students. For that purpose now I am using Listnr services. In it I just create a video on some topic and then replace the sound of that video by the sound file created in Listnr; it's so simple.
By Listnr finally I can create a better audio video effect; can provide quite attractive and easy to understand videos of related topics to my students. Just use google docs mic to convert your voice to text and copy paste in listnr voiceover, click on convert. Download the soundfile and merge in the video. All in a little time and with a little efforts. For this I use crello that time.
With my practical experience I found Listnr very useful and really the voices are too pretty for Hindi language also. Along with it I have some suggestions that can make it more useful for educators.
I think there should be auto time scaler in software like I have a video of length 1:10 secs and the listnr sound file is of 0:90 secs so system should automatically adjust the time gap between two sentences so that final play time of audio can automatically adjust to my desired time interval 1:10. This is an example. My suggestion is that the system should adjust audio file play time according the user need so that the audio file can match with the video play time. If that happens in the software It will be too convient for edu content creaters to use AI voices in their videos.
Also like others I am also seeking for a preview option in voiceovers.
Overall Listnr have enough potential to make revolution in edu industry. Wishes bright future for company.

Thanks.
