ai with python speech recognition in this we will learn about speech recognition using ai with python speech is the most basic means of adult human communication the basic goal of speech processing is to provide an interaction between human and machine speech processing system has mainly three tasksfirstspeech recognition that allows the machine to catch the wordsphrases and sentences we speak secondnatural language processing to allow the machine to understand what we speakand thirdspeech synthesis to allow the machine to speak this focuses on speech recognitionthe process of understanding the words that are spoken by human beings remember that the speech signals are captured with the help of microphone and then it has to be understood by the system building speech recognizer speech recognition or automatic speech recognition (asris the center of attention for ai projects like robotics without asrit is not possible to imagine cognitive robot interacting with human howeverit is not quite easy to build speech recognizer difficulties in developing speech recognition system developing high quality speech recognition system is really difficult problem the difficulty of speech recognition technology can be broadly characterized along number of dimensions as discussed belowsize of the vocabularysize of the vocabulary impacts the ease of developing an asr consider the following sizes of vocabulary for better understanding small size vocabulary consists of - wordsfor exampleas in voicemenu system medium size vocabulary consists of several to , of wordsfor exampleas in database-retrieval task large size vocabulary consists of several , of wordsas in general dictation task note thatthe larger the size of vocabularythe harder it is to perform recognition channel characteristicschannel quality is also an important dimension for examplehuman speech contains high bandwidth with full frequency rangewhile telephone speech consists of low bandwidth with limited frequency range note that it is harder in the latter speaking modeease of developing an asr also depends on the speaking modethat is whether the speech is in isolated word modeor connected word modeor in continuous speech mode note that continuous speech is harder to recognize
