The ease of use has been one of my favorite features about this software! I like that you can train your system to learn new words as well as phrases in order to reduce false positives later down the road. It's also nice how easy they make training their systems by just using Google Translator or typing out simple sentences into google translate, etc. However, sometimes there are minor issues where some text doesn't get transcribed correctly (sometimes even multiple times). But overall not much at all since we have had great success so far! We've used TALVALA because our clients need help keeping track of who comes through which doors in high risk areas such as schools, hospitals, government buildings, churches, etc., without them knowing exactly what was said during visits.
