This is a good way to improve vocal skills but I won't call this a communication as we are talking with the computer and there is no one on the other side to hear what we are speaking. This might create an illusion that we can talk in an effective way but I believe that we should always talk with the real person because we get to understand his expressions or even his real-time response for every sentence that we speak. Since English is not my native language, I am using the app called Opentalk and I have found it useful for the above-mentioned purpose.
Think of it this way, when you are talking to the device that you are using, whether it's a PC or a cellphone when it understands you, it translates to how well you are in speaking. I think it works on how your voice is modulated and to what extent it hears the vowels, etc. In reality, I agree that you are going to be experiencing feelings like anxiety, you might think "am I going to be understood?" I think that's the most thought about the phrase when it comes to your unnatural language. Practicing that way could be an additional plus point towards the improvement of your communication. Just researched Opentalk, and I think it's a greater way to practicing vocalizing your speech with other people, haven't tried it though.
For those who are having a hard time or are still coping with the basics of English language then this tool will surely aid you.
I use this most of the time, whether I'm using Microsoft Office: Word, or just here posting in BTCT. So my current routine is mostly like this
- Speak towards the device. "Hello World"
- Check if my grammar is correct. *Change the keyboard to Grammarly and check for errors
That's what I do most of the time when I'm on Mobile. The only pain is when you are quoting someone and it adds to your errors with the Grammarly App.
