We spoke about computer vision in sense and analyze visual information.
We're going to talk about how to teach computers to understand English today.
You may argue that they've always been able to do so.
We discussed machine language instructions and higher level 12.
While language, they also have tiny vocabulary and adhere to rigid standards.
that is completely
Naturally, this differs from human languages, which have enormous, diverse vocabulary, words with multiple meanings, speakers with various accents, and all sorts of wonderful word play.
People also make linguistic mistakes when writing and speaking, such as slurring words together, omitting essential facts, and mispronouncing terms.
But, for the most part, people are capable of overcoming these obstacles.
The ability to communicate effectively is an important aspect of what makes us human.
As a result, comprehend and speak human language has existed since the invention of computers.
Natural Language Processing, or NLP, is an interdisciplinary discipline that combines computer science and linguistics as a result of this.
Words may be arranged in a phrase.
We can't provide computers a lexicon of all potential phrases to assist them decipher what people are saying.
Deconstructing phrases into bite
which could be difficulty.
Nouns, pronouns, articles, verbs, adjectives, adverbs, prepositions, conjunctions,
These are referred to as "parts of speech."
There are subcategories as well, such as single vs. plural nouns and superlative vs. comparative adverbs, but we won't delve into that right now.
Knowing the nature words have several meanings, such be employed as nouns or verbs.
Because a computerized dictionary is insufficient to address this issue, computers must also be grammatically aware.
To do so, phrase structure rules were created, which embody a language's grammar.
In English, for example, a rule states that a sentence can have a noun phrase followed by a verb phrase.
or followed by a noun.
This type of rule may be applied to a whole language.
Then, using these principles, it's rather simple to create a parse tree, which not only identifies each word with a likely part of speech but also indicates how the phrase is put together.
For example, we now know that the noun emphasis of this phrase is "the Mongols," and that it's about their "rising" from something, in this instance "leaves."
These smaller data bits make it easier for computers to access, process, and respond to information.
Every time you make a voice search, such as "where is the nearest pizza," similar procedures are taking place.
The machine understands that this is a "where" inquiry, that you're looking for the word "pizza," and that the dimension you're interested in is "nearest."
The same logic applies to questions like giraffe?"
Computers can be fairly proficient at natural language
They can respond to queries and execute directions such as "set an alarm at 2:20" or "play T-Swizzle on Spotify."
However, as you've undoubtedly noticed, they break down when you get too sophisticated, and they can't read the text correctly or understand your goal.
Hey Siri, are your thoughts on this most pleasant mid-summer day?
This works especially well when data is kept in a web of semantic information, where items are linked to one another in meaningful connections, giving you need to create informative statements.

It has almost seventy billion facts regarding

Today, the technology is being used in customer service applications, where there are already a plethora of sample dialogues from which to learn.
People have also been using chatbots to converse with one another, with chatbots even evolving
This experiment received a lot of scary headlines, although it was merely the computers working out a simple procedure for negotiating with each other.
It wasn't malicious; instead, it was practical.
But what happens when anything is said — how can a computer decipher words from sound?
This is the field of voice recognition, which has been the subject of decades of research.
In 1952, Bell Labs unveiled Audrey, the automated

Because it was considerably faster to enter phone numbers with a finger, the project never got off the ground.

Harpy was the first computer program to identify over 1,000 words.
However, transcription was frequently 10 slower than

Deep neural networks, which we discussed the market.
Let's look at some speech, especially strategies function.
Let's begin with vowel sounds such as aaaaa...and Eeee...
These are the waveforms obtained by a computer's
This signal represents the amplitude of a microphone when sound waves force Formats.
The horizontal axis represents time, while the vertical axis represents the degree of movement, or amplitude, in this representation of sound data.
Although we can discern changes in the waveforms, it's not immediately apparent where you'd point to say, "oh ha! here is certainly an eee sound."
We need to look at the data in a new stand out.
We still have time the vertical, we plot the magnitude of the many data.
The louder the the color.
A really amazing method called the Fast Fourier Transform is used to convert waveforms to frequencies.
A spectrogram is a time - based visualization of the data.
You may have noticed that the signals have a ribbed pattern to thembecause that's my vocal tract's resonances.
I squeeze my voice chords, lips, and tongue into different or dampens distinct resonances.
This may be seen in the signal, where there are brighter and darker patches.
We can observe that the formants.
This applies to all vowel sounds.
This is the kind of data that allows computers to detect spoken vowels, and even full words.
Let's look at a more complex example, such as when I say, "she was happy."
We may also hear a variety of other unique sounds, such as "shhh" in "she," "wah" and "sss" in "was," and so on.
All of these software.
so it largely boils down to fancy pattern matching.
Then you have to separate words from one another, figure out where sentences begin and stop, and eventually you'll have voice translated to text, which will allow you to use at the start of the episode.
Because people utter words in slightly different ways owing to factors like accents and mispronunciations, using a language model, which incorporates data about word sequences, dramatically improves transcription accuracy.
"She was," for example, is more likely to be followed by an adjective such as "glad."
It's unusual for "she was" to be followed by a word right away.
If the speech recognizer couldn't decide between "happy" and "harpy," it'd go with "happy" because the language model said it was the most likely option.
Finally, we must discuss voice synthesis, or to produce speech.
This works reverse.
We can deconstruct a piece of text into its phonetic components and play those sounds back to back on a computer speaker.
"She saw me," say without emotion.
She had noticed me.
Now speak it in response to the following questions.
Who was it that saw you?
She had noticed me.
Who was it that she saw?
She had noticed me.
Was she able to see or hear you?
She had noticed me.
Although this had much 1980s, the discontinuous and difficult merging of phonemes continued to provide the trademark robotic sound.
Today's artificial voices, such as Siri, Cortana, and Alexa, have improved significantly, but they're still not quite human.
But we're so close, and it'll almost certainly be a solved problem shortly.
Especially now that we're witnessing an explosion of speech user interfaces on our phones, in our vehicles and houses, and, perhaps eventually, in our ears.
This ubiquity is creating a positive feedback loop frequently, voice, which leads to even greater accuracy... and so on.
Many people believe that in the future, voice technology will be as prevalent as screens, keyboards, trackpads, and other physical input
hat's especially excellent news for robots who don't want to have to carry around keyboards to speak with people.
However, we'll go through them in greater detail next week.Then I'll see you Next Time.
