Today we’re going to talk about how computers understand speech and speak themselves. As computers play an increasing role in our daily lives there has been an growing demand for voice user interfaces, but speech is also terribly complicated. Vocabularies are diverse, sentence structures can often dictate the meaning of certain words, and computers also have to deal with accents, mispronunciations, and many common linguistic faux pas. The field of Natural Language Processing, or NLP, attempts to solve these problems, with a number of techniques we’ll discuss today. And even though our virtual assistants like Siri, Alexa, Google Home, Bixby, and Cortana have come a long way from the first speech processing and synthesis models, there is still much room for improvement.

I am a linguist but I know nothing about computer science and NLP but I am interested to get a job in this field. Do you have any recommendations on how can I start my learning? What should I study to become more attractive towards employers?

Ayoub Essabiri says:

Dear Siri, you are not alone. I am not sure I got that too 🙂

Thatoyaone Bogopa says:

Your classes are amazing…

Yash Gala says:

Why are you talking so fast to the point it's hard to understand, people view tutorials because they have little to no knowledge of the given topic, yet you talk like your audiences are expert of the topic 🙁

Mohammad Farooq Tareen says:

Why is she talking so fast. I had to check my setting and confirm I don't have speed at 1.5

Jouna Lansman says:

'Blabbing on about'. lol I like kerryan choice pf words. 🙂

zakuro says:

Many complain about your speech being to fast, but I have to kindly disagree.
It was all perfect, fast enough and smoothly cut.

Alexandre Valente says:

Do you breath sometimes ?
Even Siri can't follow you 😉

Ashok Kumar says:

Richard S. says:

It's just crazy how much of the development of computers was helped by government. Kinda destroys the whole right wing argument about how it's only capitalism that makes a change in technology. And also, these videos are co-produced PBS, funded by the American government. If you learnt something, thank the US, I guess.
