1. What is enhanced voice
Voice assistant is one of the keys to realize the intelligent car connection, through the assistant, only the keys can be removed. One of the more typical features is the current more popular enhanced siri.
1. Enhance the difficulty of voice
1) voice synthesis technology
The performance of voice synthesis technology in the car environment is crucial. Voice synthesis adopts a hybrid unit selection system, combining the advantages of unit selection and parameter synthesis, and further improves voice quality through deep learning. The application of this technology enables voice assistants to provide a smooth and natural and easy -to -understand voice interaction experience in the internal environment.
2) Standards and methods of Voice Quality Testing in the car
According to the International Telecommunications Alliance (ITU) standards, such as ITU-T P.1100 and P.1110 P1120, these test standards cover the audio quality assessment of narrow and broadband communication without communication. The test content includes not only the clarity and sensitivity of the voice, but also to evaluate the response speed, functional integrity, system stability, and compatibility and interoperability of the system.
In particular, for Siri's testing, it also needs to pay attention to its performance in different driving scenarios, such as the accuracy of voice recognition in highways or urban transportation. In addition, user experience testing is also an indispensable part. It helps developers collect user feedback and further optimize Siri's interactive experience.
3) Build-up of the test environment
In order to ensure the accuracy and effectiveness of the test, the construction of the test environment is also very critical. Professional vehicle test laboratory can provide a simulated manual head measurement system and background noise simulation system to simulate acoustic scenes in the real driving environment. Through these tests, the user experience that the passengers can perceive by the passengers in the vehicle can be comprehensively and objectively quantified to evaluate the performance of the audio system in the car.
The rectification of these ITU failures is generally related to the SOC link, ECNR algorithm, noise reduction processing method, the whole link and audio components connected by the system, etc. The rectification of the ITU voice call quality requires high professionalism and experience, and Zhongle has a professional engineering team to escort your certification.
In summary, testing the quality of the car in the car is a multi -dimensional and multi -standard process. It requires that we must not only pay attention to the realization of technology, but also consider the user experience and the actual operating environment. Through these comprehensive tests, Siri can ensure that the best voice interactive experience in the car environment can be ensured.
