On April 8th, Jietong Huasheng was invited to attend the launch conference of "Smart Kids Daohe" Service Robot jointly held by Cixing and Ayou Culture. The company's general manager Wu Weidong represented the company's pistachio robot jointly established with Cixing and Ayou Culture. Signed a strategic cooperation agreement. This release of the U-Rabbit Robot for Children (hereinafter referred to as "Rabbit Robot") is a family service robot that can accompany children to learn and play. Jietong Huasheng provided the Lingyun ring microphone array and Lingyun intelligent voice technology for this rabbit intelligent robot, so that the rabbit intelligent robot can not only accurately recognize the owner's words, but also speak cute children's voices, let the children and the rabbit intelligent robot voice The interaction is more fluid and natural. As a highlight technology of this product, voice interaction is the main way for children to communicate with the rabbit robot. Due to the home environment where the rabbit wisdom robot is located, there are often environmental noises such as household appliances and indoor entertainment, and children may also be far and near from the rabbit wisdom robot, so the noise resistance ability of the speech recognition technology and the far field recognition ability are high Claim. In this regard, Jietong Huasheng provides the Lingzhi ring microphone array for the rabbit-intelligent robot, which can directionally acquire the children's voice, and accurately recognize the words of children in the distance through a series of technologies such as noise reduction, speech enhancement, and echo cancellation. At the same time, the adoption of Lingyun's speech synthesis technology not only enables the Rabbit Robot to speak cute children's voices, but also uses the children's voices to sing clear, transparent, and pleasant singing voices. The interactive experience between children and rabbit wisdom robots. Lingyun ring microphone array allows the robot to accurately recognize the host's words In order to allow the rabbit-intelligent robot to accurately obtain voices from all directions in the family, Jietong Huasheng specially launched the Lingyun ring microphone array. Different from the car microphone array, because the car equipment only needs to pick up the rider's words within 180 ° of the opposite side of the device, the linear microphone array can meet the demand, and the family range is more open, the speaker will move, and the sound source may be in all directions , You need to use a ring microphone array to locate and obtain voice information within 360 °. The Lingyun ring microphone array can accurately calculate the angle and distance between the sound source and the array module according to the time difference of the sound arrival, to locate the target sound source, and use the spatial filtering characteristics of the microphone array to form in the direction of the target speaker Pick up the sound beam, only pick up the signal of the beam, suppress the noise and reverberation (reflected sound) outside the beam. Since the sound energy will be attenuated as the propagation distance becomes longer, the array module organically superimposes the sound signals picked up by multiple microphones to enhance the overall picked up voice beam energy. At the same time, the use of echo cancellation technology to filter out the sound emitted by the machine's own audio equipment, input more clear and pure sound for the speech recognition engine. During the pickup process of the microphone array module, part of the environmental noise will inevitably be picked up. For this reason, Jietong Huasheng modeled the environmental noise and trained it with a large amount of real noise data to optimize the speech recognition algorithm. The Lingyun speech recognition technology with strong anti-noise ability can easily cope with common environmental noise. At the same time, the deep neural network (DNN) algorithm used by the technology can train and optimize the algorithm with accumulated voice data during user use, and continuously improve the anti-noise ability, allowing the robot to accurately recognize the owner's words. Lingyun speech synthesis allows robots to "speak and sing" In addition to using the Lingyun ring microphone array and voice recognition technology, the rabbit wisdom robot also uses Jietong Huasheng's Lingyun speech synthesis technology, which can speak cute and childlike, smooth and natural words, making people feel like a six or seven year old. The child speaks. As the earliest domestic enterprise engaged in research and application of speech synthesis technology, Jietong Huasheng launched Lingyun speech synthesis technology, which represents the top level of the industry as early as 2001. After more than ten years of technology accumulation, it has The application practice and blending in, Jietong Huasheng constantly optimizes the text analysis model and improves the rhythm planning, so that the synthesis effect of Lingyun speech synthesis technology is truly full and frustrating. The MOS value has reached 4.6, and the intelligibility, naturalness and fluency have reached the industry. Top level. Lingyun speech synthesis technology has fully supported Chinese Mandarin, English, Cantonese, Uyghur, Japanese, Korean, Russian, German, French and other 21 languages, covering more than 90% of countries and regions in the world. Mixed reading is natural and smooth, fully adapts to the current multilingual speech synthesis requirements, and allows the robot to "speak" fluent and natural words. Recently, Jietong Huasheng has launched Lingyun singing synthesis technology based on decades of deep accumulation in the field of speech synthesis. This technology can make the robot sing sweet and cute, clear and transparent, and pleasant to the ear according to the music score information. It sings like a real person, and successfully achieves the leap-forward progress of the machine from "speaking" to "singing loudly", allowing the robot to "speak" Can sing ". Letting robots learn to sing not only enhances the fun of robot services, but also means that robots have taken a big step in anthropomorphism and service experience. Lingyun platform is fully open to the robot industry As the leader of China's artificial intelligence industry, Jietong Huasheng launched hcicloud.com, the first all-round artificial intelligence open platform at home and abroad, in 2011. The Lingyun platform is fully open to the industry, and provides the industry with speech synthesis, speech recognition, OCR, handwriting recognition, face recognition, voiceprint recognition, fingerprint recognition, semantic understanding, machine translation, etc. Location artificial intelligence capabilities. Since the beginning of 2015, Jietong Huasheng announced that the Lingyun platform will be fully open to the Chinese robot industry. The domestic and foreign robot manufacturers provide a full range of Lingyun artificial intelligence capabilities services, and fully support the Chinese robot industry to build a true "can listen, speak, read, think, and judge" robot. A large number of robots that use the ability of Lingyun have been listed in batches, and more large-scale tests have been carried out in financial, telecommunications, energy government, business halls, shopping malls and other places, and have received widespread attention from the industry and users. With praise. In recent years, with the explosive growth of the artificial intelligence industry, Jietong Huasheng relies on the profound skills of artificial intelligence technology and accurate prediction of the development of the robot industry. With the concept of win-win cooperation, it does not compete with robot manufacturers for profit, let alone with robot manufacturers. The consciousness of cooperating in the market has won widespread support from domestic robot manufacturers. At present, it has established a solid partnership with most of the major domestic robot manufacturers. Lingyun artificial intelligence has become unique in the Chinese robot industry and is almost everywhere! In the future development, Jietong Huasheng will continue to rely on the artificial intelligence research power of Tsinghua University, fully respond to and support the national innovation development strategy, comprehensively promote the comprehensive docking of the Lingyun platform with the Chinese robot industry, and cooperate sincerely with all Chinese robot manufacturers. Work together to create the glory of China's robot industry.
