OneShot continuity theory and no wake-up
There are two "high-frequency words" in the test of car voice control in the past year-one shot continuous theory and no wake-up. Besides "recognition rate", they are also the most attractive voice control functions.
Have you ever wondered why you have to wake up words? Because people can easily trigger some functions in voice control in daily communication,Wake-up words are defined as a time period (after waking up to the end of the conversation), during which the speech engine will process the feedback of what you said.. Under the current voice control technology, if there is no wake-up word, you will be disturbed to autism by the voice control in the car.
Then why can’t we just call each other by their first names, just like daily communication? For example: Li Xiang, help me turn on the air conditioner. It is also because the names of two or three words are easily mistaken, which leads to false triggering of voice control.Therefore, wake-up words are usually set to "overlapping words", "greeting+name" and "so-and-so classmate" to reduce the probability of false triggering..
But this also leads to a problem-the communication mode between people is not like this at all! The picture below is the basic car voice control communication mode. Do you think it is particularly familiar?
What does OneShot mean? It’s simple.That is, wake-up words can be said together with instructions, instead of saying wake-up words first and waiting for the system to respond before giving instructions.. With the OneShot continuous speaking function, it is like this.
What does the word "no wake-up" mean?As the name implies, even the wake-up words are not needed, and you don’t need to call out the voice control function, just give instructions directly., as follows:
Did you find out that this is a process of getting closer and closer to the way people communicate, and it is also a process of getting less and less polite. Right, the way people communicate is rude.
The above is the meaning and significance of OneShot and no wake-up. And there are a few more words about wake-up-free words.At this stage, there are two main modes of wakeup-free..
Or in the music playing interface, you can just say "pause", "next song" and "increase the volume" without waking up the voice control function first.This is the most widely used wake-up-free scheme at present..
This logic is used in some models (|), Chery Arrizo GX Champion Edition, etc.) that use Iflytek voice engine.
We also see here that,In the case that most functions can give instructions directly, the system still needs to limit a time. If the time is not limited, the probability of false wake-up is still unacceptable.. Imagine that when you and the co-pilot are chatting happily about the beautiful weather today, suddenly, the system begins to talk to itself: "It’s sunny in Beijing today, and the air quality …" This situation appears twice, and you may turn off the voice control function permanently.
summarize
In the first issue of the terminology annotation series of the Internet of Vehicles, we explained several terms of voice control system and talked about their definitions, backgrounds and values. In fact, the communication between people is mostly realized by "speaking" and "listening". Of course, we also have expressions and gestures, etc. In contrast, it is even more difficult for machines to understand the meaning of expressions and gestures. Human-like interaction in the mouth of major car companies, research institutions and voice interaction solution providers is to let machines learn to understand languages, gestures and even emotions. As one of them, voice control is just in its infancy. When will we really turn "processing" into "understanding", and we will enter the next more intelligent stage. (Photo/Text car home Zheng Xu)
