Just saying, working touch screens have been around on devices for 30 years or more. Most 'PDA's, including < $100 phonebooks had decent resistive touch screens as far back as the mid-90s. Also, as such, speech recognition too has been around for at least 25 years. What's new in today's smartphones is the cloud+deep learning driven high-accuracy. You could probably have easily found a handheld with touchscreen and speech recognition at Circuit City in 1999.
