🍣 Thousands of Japanese Sentences 🍣
I listen to each audio file carefully a few times and throw out all the ones that do not sound natural before creating these videos.
One problem with some foreign language study channels on YouTube is that they use TTS without informing their audience. I've heard a number of errors on videos, so those using those videos are learning things that are not correct. As TTS gets better and sounds more and more like native speakers, you need to be very careful not to be deceived.
* For videos aimed at language study, the audience should be informed, so they will know that there is a chance that the "spoken" sentence may be wrong or sound unnatural.
* For videos used for language study, a native-speaker should proof-listen to all the audio, throwing out any unnatural-sounding audio files before creating the video.
