We have transitioned to a complete manual process for transcription from an mixed automated and manual process. This means

  • No more screening of the files
  • Flat 0.50 per minute rate for all kinds files
  • Improvements in quality of transcripts

Transcript orders can be placed from the uploaded records page. Earlier it was from the transcript page which used to list all the screened recordings.

The limit of 60 seconds on transcripts orders has also been removed. Transcript orders can now be placed for files of any length.

Sample Call Graph Transcript – Born To Misrepresent Podcast

Click to play

This podcast was recorded last year when we had just launched Call Graph. We finally found some time to transcribe it with our system and post it here.

A couple of points about our transcription.

  • It is time coded.
  • The words which cannot be transcribed are timestamped and marked with blank ____.
  • Its provided in Word, PDF and Open Office Document formats.
  • If names of the speakers are mentioned then we use their initials. Otherwise we use Speaker 1, Speaker 2 etc.

One Year of Call Graph, Five Lessons Learnt The Hard Way

Tuesday, March 24th, 2009

We crossed an important milestone this month: we made it into the second year! The Call Graph client was launched on March 8th 2008 in the first edition of DevCamp Bangalore. We launched the services part few months later, paid plans in November and since then we have been making revenues. Today Call Graph is mostly a ‘Ramen profitable‘ venture. That is, the revenues are just enough to sustain our operations and meet our living costs. The last year has been an incredible learning experience. We made mistakes, stumbled, recovered and somehow managed to survive. Not sure if we can keep doing that given the worsening economy, but for the time being, here are few lessons that we’ve learnt the hard way.

Its The Business Stupid

A new venture is always about creating a sustainable business.  It is almost never about the product or the service. Its about keeping enough coming in so that you can grow and get better with time. Coming from an engineering background its a very hard lesson to learn. The focus is always more on the product. The product is obviously very important. But never ever lose sight of the business. If the product is not creating a sustainable business then maybe you’re doing it wrong.

You’ll Be Lucky To Have One Percent Conversion Rate

For any internet product or service, its assumed that you’ll have a conversion rate of one percent. It could be number of paid to free users, signed up users to active users, etc. In our case it is the number of downloads to the number of registered users. We haven’t been able to achieve that 1 percent conversion rate yet. There are variety of reasons for that, one of the most important being the large number of international users. Its a simple chicken and egg problem. Support for Internationalization requires effort but we cant do it since we don’t have the resources and so on.

Free == Substandard Product

Its assumed that everything on the internet expected to be free. What we found was, giving it away for free creates this impression that its somehow substandard. This is especially true if your competitors charge. For Call Graph the business proposition necessitated that we offer it for free. But we had a incredibly hard time dispelling this illusion. Adding a purchase option helped a lot. That is in fact our most popular plan.

Turning Cash Flow Positive Is A Moving Target

Its never ever that one single feature or that one plan which does the trick for you. By the time you implement it, things have changed and the potential customers have disappeared. It’s rather a culmination of all those features and plan which add up. What we’ve learnt is to never rely on a single source of revenue. Especially in these recession times. You never know which one is going to earn your bread on any particular day!

Its A Survival Game

Someone once said that the first 3 years of a startup’s life are the toughest. After that you just get used to it! That statement sums it up. The world out there is tough and you need to evolve yourself with the only goal of surviving. Like as it happens in Cricket One Dayers, batting through the 50 overs matters the most. The more you’re out there, the bigger are the chances of making it.

Finally a big thanks to all our users who have helped us reach here. Thanks to all those who tried out Call Graph, pointed out the bugs and deficiencies and helped us improve it. You are simply the best!

Transcription Settings

Monday, August 4th, 2008

For high quality voice recordings of your Skype conversation, please use the following settings

  • Recording Mode: Stereo – 2 channels
  • Sampling Rate: 16000 Hz
  • Bit Rate: 128 kbps

The first three can be configured from the ‘Recording’ tab of the configuration dialog. The last two are in the ‘Advanced’ Tab.

Tips:

  • First and foremost, use a headset instead of the inbuilt speaker and mic. It helps to keep the background noise to the minimum and reduces the possibility of any echo during the call.
  • If you get an echo then drop the call and try again. If possible, record a test call first and play it back to make sure things are fine.
  • For SkypeOut and Conference calls, ensure that the call quality is good enough before you start the recording. Make a few test calls before the actual one if possible.
  • Close all other applications which might use your internet bandwidth during that period. Usual browsing should not interfere but downloads or uploads (or BitTorrent) severely hampers the call quality.
  • If possible, reboot your machine once before you start on the call. It clears up the memory and performs better.
  • Finally, keep an eye on the status displayed at the bottom of the Toolbar as well during the call. It should be showing ‘Recording in progress’. If not restart the call and the recording.

Explanation:

Technically speaking, these settings are optimal for our system. The Speech Recognition engine that we use works in the wideband mode (16 kHz) and the 128 kbps bit rate preserves the optimal voice quality in the mp3 files. Encoding in two track mode enables us to split up each of the track separately and process them.
