Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] An acoustic-based text input recognition method for smart devices, comprising the following steps: (S1) using fingers to input text characters in a text input area, and collecting sound wave signals; (S2) processing the collected sound wave signals; (S3) Acoustic signal for identification.

[0019] In the step (S3), the envelope of the sound wave signal is extracted, and the envelope features of different characters are extracted, the sound wave signal is transformed, the frequency domain characteristics of the collected signal are analyzed, and the frequencies of different characters are extracted Features, and through the synthesis of the above features, model training is performed on the character feature data. When the user inputs according to the grammatical rules, the character input by the user is recognized by comparing the exist...

Abstract

The present invention relates to the field of intelligent recognition, which discloses a text input recognition method for smart devices based on acoustics, including the following steps: (S1) using fingers to input text characters in the text input area, and collecting sound wave signals; (S2) collecting sound waves processing the sound wave signal; (S3) identifying the sound wave signal. It provides a sound wave signal recognition method with good user experience and light and strong anti-noise equipment, thereby improving the efficiency of text recognition.

Description

technical field [0001] The invention relates to the field of intelligent recognition, in particular to an acoustic-based text input recognition method for smart devices. Background technique [0002] Nowadays, with the rapid development of computer technology and wearable smart device industry, smart devices are gradually popularized in people's lives, and smart devices have more and more functions, and their data processing capabilities are becoming more and more powerful. At the same time, these devices are small in size Getting smaller and smaller. While the miniaturization of smart devices brings a lot of convenience, when text input is required for interaction, some traditional text input methods can no longer adapt well to the new input environment. Looking for a new and better text input The method appears to be extremely urgent. [0003] After recent years of development, the form of wearable devices is gradually improving. Among them, the form of interaction has ...
