Speech recognition (SR) is the translation of spoken words into text. It is also known as "automatic speech recognition", "ASR", "computer speech recognition", "speech to text", or "STT".
Speech recognition systems made more than 10 years ago also faced a choice between discrete and continuous speech. It is much easier for the program to understand words when we speak them separately, with a distinct pause between each one. However, most users prefer to speak in a normal, conversational speed. Most modern systems are capable of understanding continuous speech.
This report looks at the patenting activity around voice control of mobile devices and also captures key litigations and NPE’s operating in this area.
Innovation however, in the voice recognition space has been going on since many years and in this report we take a look at 20 year patenting activity on voice recognition and voice commands to mobile devices over US patent database.
