Hi Everyone! Our app is designed to be used at site and I always felt that response speed is critical for seamless app use

It appeared to be a compromise. This specially relates to audio and TTS we use. We can use very naturally sounding TTS models, but they may take about 1 minute to respond. Or we can use something which responds in 5 seconds but quality will be lower. How much do you think a user can wait for response before she shuts down the app as it takes too long?
