I am looking for a good face, emotion and voice recognition method in C#
. For face recognition I was early using Emgu CV which is not accurate and performance is ve
It seems that you need Kinect. http://www.microsoft.com/en-us/kinectforwindows/develop/
Simply take a look at System.Speech.Recognition Namespace (look at this and this answer).
I understand the question is very old, although I would like to contribute to it since I am also working on similar application
For Face, Emotion and Voice recognition there are plenty available now, find below some options
1) Face detection and recognition using OpenCV: http://ahmedopeyemi.com/main/face-detection-and-recognition-in-c-using-emgucv-3-0-opencv-wrapper-part-1/
Pro: Open source so basically free. You can modify the code to accommodate your needs. Multiple platforms supported.
Con: Accuracy is tolerable but not great. This can be resolved by modifying the library to your needs.
2) Face detection and recognition with emotions: try Microsoft Cognition Service API
Pro: very accurate. It includes many other services such as NLP, Speech to Text, Text to Speech, Computer Vision, RT language translator and so on. Accuracy is great since the services are hosted on cloud and are being trained for every data input.
Con: Paid solution. Little expensive. You have to pay for each service separately.
3) Speech recognition: Google Voice API Pro: similar to MS cognition service. Accuracy is better in Noise. con: Paid. May not be good for one time sale commercial product
4) Speech recognition and NLP: wit.ai/api.ai Pro: Free to use. Can use data from other public apps. Accuracy is good. Con: I don't find find any
