问题 I was reading this paper on environmental noise discrimination using Convolution Neural Networks and wanted to reproduce their results. They convert WAV files into log-scaled mel spectrograms. How do you do this? I am able to convert a WAV file to a mel spectrogram y, sr = librosa.load('audio/100263-2-0-117.wav',duration=3) ps = librosa.feature.melspectrogram(y=y, sr=sr) librosa.display.specshow(ps, y_axis='mel', x_axis='time') I am also able to display it as a log scaled spectrogram: librosa

问题 I make an app in English. My app uses Speech recognition. But if I install this app on device with another system language, French or Russian for example. My speech recognition doesn't work. It works only for language which by default in system. How can I make English language for Speech recognition by default for my app? I found this method but it doesn't work Locale myLocale; myLocale = new Locale("English (US)", "en_US"); Locale.setDefault(myLocale); android.content.res.Configuration

问题 What is the best way to transcribe medium/large audio files, ~ 6-10 mins each file, using Microsoft Speech API? Something like batch audio files transcription? I have used the code provided in https://docs.microsoft.com/en-us/azure/cognitive-services/speech-service/speech-to-text-sample, for continuously transcribing speech, but it stops transcribing at some point. Is there any restriction on the transcription? I am only using the free trial account atm. Btw, I assume there is no difference

问题 I am creating a Text to Speech system for a phonetic language called "Kannada" and I plan to train it with a Neural Network. The input is a word/phrase while the output is the corresponding audio. While implementing the Network, I was thinking the input should be the segmented characters of the word/phrase as the output pronunciation only depends on the characters that make up the word, unlike English where we have slient words and Part of Speech to consider. However, I do not know how I

问题 I'm using pocketsphinx with raspberry pi for home automation. I've written a simple JSGF grammar file with the supported commands. Now, I want to use an activation phrase such as "hey computer" prior to the commands, to avoid false detections and only perform speech recognition once the activation phrase has been spoken. If I'm not getting this wrong, pocketsphinx supports two modes for speech recognition: keyword spotting mode, and language model / JSGF grammar mode. In pocketsphinx FAQ when

问题 I used speech_recognition.AudioFile in Python 3.6 , but this error was indicated: AttributeError: module 'speech_recognition' has no attribute 'AudioFile' This is my code: #!/usr/bin/env python3 import speech_recognition as sr # obtain path to "english.wav" in the same folder as this script from os import path AUDIO_FILE = path.join(path.dirname(path.realpath(__file__)), "english.wav") # AUDIO_FILE = path.join(path.dirname(path.realpath(__file__)), "french.aiff") # AUDIO_FILE = path.join(path

问题 I am trying to install HTK Toolkit in my windows 10 machine. It has a prerequisite of: Ensure that your PATH contains C:\Program Files\Microsoft Visual Studio\VC98\bin I installed Microsoft Visual studios but I am not able to find the VC98 folder(file) in location where my visual studio is installed. I tried to search it a lot of times, but still I was unsuccessful in finding it. Can someone please solve this for me. My final goal is to install HTK Installing HTK on Microsoft Windows

问题 I did coding as below. however I want to know whether there is some ways to control the recording duration. I actually, want to have a program which has a start & finish buttons so that I can control to record. I know that it is like an elementary question. but I really need to solve it. help me~ how should I compensate this problem? import speech_recognition as sr r = sr.Recognizer() mic = sr.Microphone() show = input("enter text: ") print("Read text\a") with mic as source: audio = r.listen
