According to the latest report of the Topology Industry Research Institute, voice interaction has become the entrance to the intelligent era. From 2014 to 2017, global voice equipment shipments have risen sharply. Global shipments will be less than 5 million units in 2014 and shipments will reach 25 million units in 2017. From 2016 to 2021, the annual compound growth of the global speech recognition market will reach 43.6%. Speech recognition belongs to the basic application layer in the middle of artificial intelligence. This layer is distributed with speech recognition, NLP, machine vision and so on.
Figure 1: The growth trend of the speech recognition market.
Wang Dong, deputy director of Tsinghua's Speech Language Lab, believes that speech recognition is actually a branch of artificial intelligence. We hope to achieve more natural communication when interacting with machines, rather than typing through text, which is an essential part in the future. Intelligent means of interaction. The biggest difference between the current speech recognition and the past is that the whole system does not have so many complicated modules. The neural network basically learns from the speech signal to the end-to-end of the speech content. Due to the introduction of deep learning, the performance of the speech recognition system has been greatly improved.

In the field of smart phones and smart homes, voice recognition is a means to improve the user experience, but it should not be overlooked that the display is a key feature of the experience of smart phones, how the relationship between the two develops. The latest statement from Apple's vice president shows that the two are not available. Smart voice can be used to insert wings into the mobile phone experience and home experience, but the voice recognition without the display seems to be slightly monotonous.
On May 6th, Apple's global marketing vice president Phil Schiller said that the lack of display screens for dedicated intelligent voice devices such as Amazon Echo is a hindrance in many cases. Just as people are accustomed to using a smart phone, and then pick up the previous Nokia's feature phone, I always feel that it is inconvenient to use.

He said that Apple is firmly optimistic about voice assistants, saying that Apple's continued development of Siri is the best example. Schiller also mentioned the rapid development of pure voice assistant devices that have no screen and only support voice operations such as Amazon Echo and Google Home.
“Sometimes, when you can't use the display, it's more convenient to use only the voice. For example, when you are driving, or when you are walking around the house, you want Siri to cut the song for you, not to run back. But even so, voice The assistant's lack of a screen will still limit its usefulness," Schiller said.
“The voice assistant is very convenient for many times, but that doesn't mean you never need a screen,†he said. “So I think that no screen is not suitable in many cases.â€
Currently, Siri only supports devices with displays. Last year, Siri landed on a Mac as part of the macOS Sierra system.
Schiller took the Apple map as an example. He said that when navigating on AppleWatch and CarPlay, the voice assistant can provide voice instructions, but the live map can help users better understand the surrounding environment.
Schiller also mentioned photography, saying that having a display is more beneficial to end users.
“Like photography, it’s one of the main reasons people buy our products, and photography requires a screen,†he said. “In the various photos we share, devices without screens are not very useful. Today, there are more and more photos on social apps, so their experience on pure voice devices is not so good.â€
For the best experience, Apple is quite a voice. With the rise of China's manufacturing, especially the breakthroughs in hardware and software systems of local companies such as Huawei and Tencent, I believe that Chinese manufacturers will have their own upgrades in the future. sound.
