I was tried so many stuffs from the internet but couldn't found some specific problem so please help me about below error! ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.rear ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.center_lfe ALSA lib pcm.c:2495:(snd_pcm_open_noupdate) Unknown PCM cards.pcm.side ALSA lib pcm.c:2495:(snd

问题 I'm building a C# .net application for STT and I'm creating credentials manually. I find the documentation hugely confusing for me and I dont know how to add the credentials properly. I added a project, created a json credential and downloaded and kept on a folder and pointing to it for manually with GoogleCredential for authorization and everythings working good. But this cant be a solution for a shipped app. Current approach: GoogleCredential credentials = GoogleCredential.FromFile(Path

问题 Can be get an audio signal back from its MFCC coefficients? Also do MFCC coefficients have a range of value if so what is it and if not how do you normalize it between 0 to 1. I tried using the following MATLAB code: http://labrosa.ee.columbia.edu/matlab/rastamat/ but the recovered audio is no where similar to the original signal. 回答1: This question better fits dsp stackexchange. You can not repair exact signal from MFCC, it drops some information on the way so the signal must be similar but

问题 I am not sure about some documentation related stuff. To sum up what I did and what I want to to: I managed to introduce voice recognition feature into an Android application that is running on Android 4.2 on a tablet, and it works ok. Now I want to port my application on Google Glass but unfortunately I get the following error when I try to start the speech recognizer: error 5 -> ERROR_CLIENT (Other client side errors). The message guides me to find other errors that not related to

问题 Hi i'm currently developing a program that is supposed to recognize my voice and then write down what it hears, but when i run the code and i click the buttun to start the recEngine it says that "An unhandled exception of type 'System.NullReferenceException' occurred in System.Speech.dll", and in the tips it says that it's possible that the var was null before. But i have setted the variable before or am i doing something wrong. Here is the Code using System; using System.Windows.Forms; using

问题 I'd like to be able to end a Google speech-to-text stream (created with streamingRecognize), and get back the pending SR (speech recognition) results. In a nutshell, the relevant Node.js code: // create SR stream const stream = speechClient.streamingRecognize(request); // observe data event const dataPromise = new Promise(resolve => stream.on('data', resolve)); // observe error event const errorPromise = new Promise((resolve, reject) => stream.on('error', reject)); // observe finish event
