This is a server for highly accurate offline speech recognition using Kaldi and Vosk-API. This approach works on the assumption that a speech signal, when viewed on a short enough timescale (say, ten milliseconds), can be reasonably approximated as a stationary processthat is, a process in which statistical properties do not change over time. VOSK Models Models We have two types of models - big and small, small models are ideal for some limited task on mobile applications. The example below uses Google Speech Recognition engine, which I've tested for the English language. For example, given the above output, if you want to use the microphone called front, which has index 3 in the list, you would create a microphone instance like this: For most projects, though, youll probably want to use the default system microphone. First, a list of words, a maximum number of allowed guesses and a prompt limit are declared: Next, a Recognizer and Microphone instance is created and a random word is chosen from WORDS: After printing some instructions and waiting for 3 three seconds, a for loop is used to manage each user attempt at guessing the chosen word. welcome to another video, in this video I'll be showing you what you need to use vosk to do speech recognition in Python! We need to install the other packages manually. Runs some "baseline" audio files through the recognizer to get the x-vectors, Run some testing audio files through the recognizer to get x-vectors to test with, Run each test x-vector against each "baseline" x-vector with the cosine_dist function, Average the speaker distances returned from cosine_dist to get the average speaker distance.

The cosine_dist function returns a "speaker distance" that tells you how different the two x-vectors were. In my program, I then use these vectors in the vector list as the reference speakers that are compared with other x-vectors in the cosine_dist function. The first thing inside the for loop is another for loop that prompts the user at most PROMPT_LIMIT times for a guess, attempting to recognize the input each time with the recognize_speech_from_mic() function and storing the dictionary returned to the local variable guess. For example, the following recognizes French speech in an audio file: Only the following methods accept a language keyword argument: To find out which language tags are supported by the API you are using, youll have to consult the corresponding documentation. Or class tokens? The first component of speech recognition is, of course, speech. Hence, that portion of the stream is consumed before you call record() to capture the data.
