Great tips on how to optimize the Skype connection with a visual step by step guide. Here’s some additional one’s if you are using Call Graph.

  • Record in the stereo mode and 16 KHz sampling rate. In the stereo mode incoming/outgoing voice data is encoding in a separate tracks which makes post editing a lot less painful.
  • Use a headset instead of the inbuilt speaker and microphone of your laptop/notebook. Keeps unwanted noises down to the minimum.
  • Keep the stats window open and keep an eye on it. If anything goes wrong during the recording, it will show up there.

And get it transcribed by us once the recording is done! its much easier to read through it than listen to it. :)

Call Graph Web Service Introduction

Monday, July 7th, 2008

The Call Graph web service is now open for everyone. Here’s a short introduction.

The purpose: it gives you storage, sharing, search and transcription services for your Skype calls recorded with our Call Graph Skype call recorder. Here’s how it works. You first sign up for the service, then download our Skype call recording client, associate the client with the your account on CRIMS and magically all your Skype calls will start appearing on the site. You can do various things with it after that, the most useful being search and generate transcripts.

The search is done through our keyword mining technology. We process the call record and generate a list of keywords for the call. The call is then indexed with these keywords. So if you used the word “Call Graph” several times during a call then both call and graph would become a keywords for it. Few months down the line if you want to locate this particular call, you just search for graph and you’ll get it back.

The transcripts are a bit more tricky thing though. The first pass is through a Automatic Speech Recognition engine. It processes the call and generates an output. Then we manually proof read the transcripts and correct all the errors. Right now the manual effort required is very high but we are hoping that as we improve the system we will be able to gradually reduce this manual effort.

Its important to note that we do try and protect the confidentiality of the call records. Even though its being heard by a person, we ensure that a single person does not go through the whole call. We use various methods to ensure that. Also, till you order the transcripts the call record is machine processed. So you have a control on which call records can be heard and which one’s cannot be.

Apart from these, you can also choose to just archive your call records and keep them for posterity. Or share them with anyone else without having to attach in your mail or upload it to some file sharing website.

We provide these services for free for the time being. Read up on our FAQ to know more. So please sign up and let us know what you think of it.
