ESP-Skainet感受声音赋予物体的意义自定义命令词，唤醒你的智慧生活。
AIoT智能物联网解决方案，ESP-Skainet智能语音助手，可支持唤醒词引擎(WakeNet)，离线语音命令识别引擎(MultiNet)和前端声学算法。Skainet将ESP32与人工智能(AI)语音识别相结合，是完整的AIoT解决方案的一部分。
完整的人机对话包括对声音信号进行前端处理，将声音转换为文本进行机器处理，并在机器生成语言后利用语音合成技术将文本语言转换为声波，从而形成完整的人机语音交互。机器“听”本质上是一项对声音特征和文本进行分类的任务。
[En]
The complete man-machine dialogue includes the front-end processing of the sound signal, the conversion of sound into text for machine processing, and the use of speech synthesis technology to transform the text language into sound waves after the machine generates the language, thus forming a complete human-computer voice interaction. Machine “hearing” is essentially a task of classifying sound features and text.
人类听觉形成的过程是将声能转化为机械能，再转化为生物电信号，在听觉中枢进行处理和分析的过程，而机器的听觉则通过音频信号、音频信号和电信号的特征向量解码为文本理解。如果机器需要感知声音和音色等特征的开始和结束，它还需要进行额外的信号处理和特征分类任务。
[En]
The process of human hearing formation is the result of transforming sound energy into mechanical energy, and then into bioelectric signals, which are processed and analyzed in the auditory center, while the “hearing” of machines is decoded into text understanding by the feature vector of audio signals, audio signals and electrical signals. If the machine needs to perceive the start and end of sound and timbre and other features, it also needs to carry out additional signal processing and feature classification tasks.

智能语音助手可以为多种智能终端赋能，构建全产业生态链。消费者智能语音交互是人们获取智能语音最常见的渠道，从手机语音助手、家庭智能音箱、智能耳机、智能电视、故事机到智能汽车等。
[En]
Intelligent voice assistant can empower many kinds of intelligent terminals to build the whole industry ecological chain. Consumer intelligent voice interaction is the most common channel for people to access intelligent voice, from mobile phone voice assistant, home intelligent speaker, smart headset, smart TV, story machine to intelligent car and so on.
在智能终端的背后，是一个广阔的生态，包括开发者的开放语音平台、语音操作系统和音频内容等。语音助手是终端的语音控制程序，它通过智能对话和即时问答之间的智能交互，让智能助手帮助完成用户分配的任务。
[En]
Behind the intelligent terminal, there is a broad ecology, including open voice platform for developers, voice operating system and audio content and so on. The voice assistant is a voice control program for the terminal, which allows the intelligent assistant to help complete the tasks assigned by the user through the intelligent interaction between intelligent dialogue and instant question and answer.
在智能家居中，让智能门锁记住你的声音，为家人提供更可靠的安全保护；只需简单地说一声“回家”和“出门”，智能插座和开关就会自动开启或关闭；空调、冰箱、灯具都会听从你的命令，在不同的模式之间轻松切换。
[En]
In the smart home, let the smart door lock remember your voice and provide more reliable security protection for your family; simply say “home” and “go out”, the smart sockets and switches will be turned on or off automatically; air conditioners, refrigerators and lamps will all follow your command and easily switch between different modes.
当智慧办公时，语音切换办公资源，提高各类资源的使用效率，降低功耗；语音控制显示屏、电话等办公设备，让办公充满科技感；解放双手，录音，工作更高效。
[En]
When smart office, voice switch office resources, improve the efficiency of all kinds of resources, reduce power consumption; voice control display screens, telephones and other office equipment, make the office full of science and technology; liberate hands, audio recording, work more efficiently.
陪伴设备的应用，让孩子多一个朋友的呼唤，也就是到身边。让陪伴更加丰富多彩，在故事、成语、唐诗、儿歌和舞蹈之间随意切换。给老人更多温暖，陪伴他们，照顾好他们。让老人也与时俱进，查天气、听歌剧、陪聊天、紧急闹钟，一个电话，不再寂寞。
[En]
Accompany the device application, let the child one more friend call, namely to the side. Make companionship more colorful, switch between stories, idioms, Tang poems, children’s songs and dances as you like. Give the elderly more warmth to accompany them and take good care of them. Let the elderly also be in line with the times, check the weather, listen to opera, accompany chat, emergency alarm, a call, no longer lonely.
语音助手不断向家庭、车载、可穿戴设备等领域延伸和迁移，构建全行业生态链。通过语音助手或语音传输功能提供音频内容和任务处理服务。
[En]
Voice assistants continue to extend and migrate to home, vehicle, wearable devices and other fields to build an industry-wide ecological chain. Provide audio content and task processing services through voice assistant or voice transfer capability.
智能语音能力的消费硬件可以分为智能家居、儿童产品、便携产品、车载设备、商务产品等。有些产品的交互功能更强，需要通过语音交互为用户提供音频内容和一些任务处理操作。
[En]
The consumer hardware of intelligent voice ability can be divided into smart home, children’s products, portable products, car equipment, business products and so on. Some products have stronger interactive features, and need to provide users with audio content and some task processing operations through voice interaction.
例如智能音箱与车载设备可用于控制开关、收听FM、导航等；部分产品的功能性更强，例如智能录音笔的核心功能是为用户提供语音转文字服务。
为语音交互蓝图铺平道路，成为智慧生活的入口。智能音箱应用数量有限，品类较少，潜在的应用想象空间还比较空白，同时信息量大的服务不易通过语音交互，成为智能音箱应用引流的考验。
[En]
Pave the way for voice interaction blueprint and become the entrance to intelligent life. The number of intelligent speaker applications is limited, the category is less, the potential application imagination space is still relatively blank, at the same time, the service with large amount of information is not easy to interact through voice, which has become the test of intelligent speaker application drainage.
