Speech recognition with Microsoft Cognitive Speech API and non-microphone real-time audio stream

阅读更多关于 Speech recognition with Microsoft Cognitive Speech API and non-microphone real-time audio stream

问题 Problem My project consists of a desktop application that records audio in real-time, for which I intend to receive real-time recognition feedback from an API. With a microphone , a real-time implementation using Microsoft's new Speech-to-Text API is trivial, with my scenario differing from that only in the sense that my data is written to a MemoryStream object. API Support This article explains how to implement the API's Recognizer (link) with custom audio streams , which invariably requires

CSCore loopback recording when muted

阅读更多关于 CSCore loopback recording when muted

问题 I'm using CSCore.WasapiLoopbackCapture to record system sound. But when there is no sound in system, it doesn't record at all! For instance, while playing music and recording it, the output file's duration is less than the track's. I want it to continue recording even when there is no sound in the system but I didn't find any property to control this behavior. Here is my code snippet: WasapiCapture waveLoop = new WasapiLoopbackCapture(); waveLoop.Initialize(); waveLoop.DataAvailable +=

问题 First of all: I found already this question: Is it possible to capture audio output and apply effects to it?. But it does not answer my question. My problem: I've asked how to record the audio output with cscore a few month ago: C# recording audio from soundcard. All that works fine, but now I would like to extend my application. I would like to offer the ability to apply effects to the recorded audio in realtime. I've already found this documentation: http://cscore.codeplex.com/wikipage

How to set speaker sound enhancement settings

阅读更多关于 How to set speaker sound enhancement settings

问题 How can I programatically set those sound effects available from the Windows Speaker Settings (Enhancements tab)? 回答1: I am afraid of that this is not possible. See the comment of Maurits on his blog. Each endpoint has two property stores; the "endpoint property store" displayed above, and the "effects property store." The endpoint property store is exposed to applications, but the effects property store is limited to: 1) the audio driver 2) the audio engine 3) the Sound control panel. So
