Google Speech API streaming audio exceeding 1 minute
问题 I would like to be able to extract utternaces of a person from a stream of telephone audio. The phone audio is routed to my server which then creates a streaming recognition request. How can I tell when a word exists as part of a complete utterance or is part of an utterance currently being transcribed? Should I compare timestamps between words? Will the API continue to return interim results even if there is no speech for a certain amount of time in the streaming phone audio? How can I

chrome speech recognition WebKitSpeechRecognition() not accepting input of fake audio device --use-file-for-fake-audio-capture or audio file
问题 I would like to use chrome speech recognition WebKitSpeechRecognition() with the input of an audio file for testing purposes. I could use a virtual microphone but this is really hacky and hard to implement with automation, but when I tested it everything worked fine and the speechrecognition converted my audio file to text. now I wanted to use the following chrome arguments: --use-file-for-fake-audio-capture="C:/url/to/audio.wav" --use-fake-device-for-media-stream --use-fake-ui-for-media
measuring rate of speech in realtime
问题 I'm looking for a quick and simple way to measure the rate at which I am speaking in real time. Course grained approaches or approximations are sufficient. The idea is to write a simple app/widget that at least tells you to speed up or slow down while speaking. Measuring things like pitch and volume might also be nice. I assume this can be done simply with a variety of speech recognition libraries, but I am familiar with none of them and quick glances at the documentation do not give a simple

IBM Watson Speech to Text Service is not giving response in Unity3d
问题 I have an ExampleSstreaming class which actually I got from GitHub of IBM Watson SDK (speech to text service demo).

How to specify phonetic keywords for IBM Watson speech2text service?
问题 While we have had good success with Bluemix Java SDK in the general case, we've bumped into problems while trying to recognize occasional non-English words (e.g., foreign last names). Our hope was that one could specify the keyword list using SPR phonetic notation (which works great for text2speech), but that does not seem to be supported for speech2text. Any suggestions/workarounds? SpeechToText service = new SpeechToText(); service.setUsernameAndPassword("USERNAME", "PASSWORD"); File audio
Mp3 / Wav to Text
问题 I currently have a mobile application that can record speech as either a WAV or MP3 and would like to convert it to text. I have looked around - Microsoft Speech, UCMA, etc -- but haven't seen any good examples of how to do it. Can someone help out here? FYI - We have access to MS Lync. Look forward to any responses, James 回答1: There's a sample of using the UCMA 3.0 SDK to perform speech recognition, available here. However, from experience (and I've love to be proved wrong here) you can only
