What are computers for?
	- entertainment
	- communication
	- navigation
	- science
		+ unlocks whole new frontier in what is calculatable, what is doable
		+ "big data", but slightly irrelevant to topic

Why do Computers need to understand language?
	- Just like we use language to communicate meaning/intent to other people, language is one of the ways we can interact with our tools/computers
	- Computers can even be a language aid
		+ language translation
		+ emails, voice transcription
		+ voice recording/sending
		+ hearing aids
	- or we can use it to turn natural language into computer queries to make certain tasks easier (information/action)
		+ "What's the temperature at 2pm tomorrow?"
		+ "What time is the next bus?"
		+ "When does Presti's Bakery close on Wednesday?"
		+ "Call Mom"
		+ "Text Dad to buy cat food"
		+ "Turn on the kitchen lights"

Popular Example
	- Virtual Assistants (siri/alexa/google assistant)
	- watson

Speech Synthesis
	- vocaloids

Natural Language Processing (NLP)
	- google translate
	- turning voice sample into machine queries
	- understanding user intent

Speech Recognition

Difficulties with V

Common Types
- recording words, putting them together
- recording individual phonetics

	+ show live demo?

Where is it commonly used?
- trains
- smart assistants (hey google/siri/alexa)
- smart devices

Popular example, siri
- siri was actually not originally from apple, was originally an app (SRI international AI center)
- show siri timeline (https://en.wikipedia.org/wiki/Siri)
- siri original VA didn't realize she was the voice of siri (https://www.youtube.com/watch?v=QP-iVhdXjPk)
- show change of siri voice over time (https://www.youtube.com/watch?v=QP-iVhdXjPk)
- usecases, how "natural" it's become over the years
- https://www.youtube.com/watch?v=4ryQTkDWmBg
- side tangent: apple fumbled user voice data to google/amazon, who were able to improve voice recognition/naturalness
	+ even led to apple being seen as "stagnant" (https://www.youtube.com/watch?v=4ryQTkDWmBg)
- siri delay (https://www.youtube.com/watch?v=nSdvj6yphoY)
- siri not originally created for voice assistant, but rather just "voice recognition"
