Online to offline service in response to voice requests
A recently granted patent (Publication Number: US11984118B2) discloses an artificial intelligent system designed to provide online to offline services in response to voice requests from user terminals. The system comprises electronic devices with information exchange ports, storage mediums, and processors. When a voice request is received, the system utilizes customized and general recognition models to determine a literal destination associated with the request. This information is then used to generate electronic signals containing the destination and a triggering code, which is sent to the user terminal to prompt the application to display the destination on the interface. The system's processor is further directed to update the customized recognition model in response to voice requests and utilize data from historical online to offline services to enhance the recognition process.
Moreover, the system incorporates customized and general language models to determine the literal destination based on acoustic probabilities and literal probabilities derived from the recognition models. The general recognition model is trained using data obtained from the general public, while the customized model is based on points of interest associated with the user terminal. The system's processor is also tasked with identifying candidate literal sequences with the highest sequence probability to establish the final destination. Additionally, the system can determine acoustic results of the voice request and update the customized recognition model accordingly. Overall, the patented system aims to streamline the process of providing online to offline services through voice commands, leveraging advanced AI technology and recognition models to enhance user experience and accuracy in destination determination.
