We are pleased to announce we have recently expanded our text to speech (TTS) capabilities by the addition of a third TTS engine choice – from IVONA Software.

With the addition of IVONA TTS, we are able to offer many more language options for developers. Here is a list of what is currently available:

  • Danish
  • Dutch
  • UK English
  • US English
  • Welsh English
  • Australian English
  • Indian English
  • French
  • Canadian French
  • German

The TTS documentation page gives further detail on choosing and using a TTS voice, including a link to a tool that will play samples of the voices available for a particular language or gender allowing a comparison to be made.

More voices are in the pipeline from IVONA. Take a look at their website to see what’s coming. If you don’t see the language you need then let us know.

Happy developing.

G.729 media codec now available for Aculab Cloud

We are pleased to announce that we are now able to offer the G.729 codec for use with our UAS APIs to customers who have a requirement for it.

The default codec for the Aculab Cloud platform is G.711, which uses 64kbit/s upstream/downstream rates to transmit the voice signals to/from the end user. G.711 is the default codec for the PSTN, and also for SIP-based phone systems. There are, however, tens if not hundreds of other voice codecs in existence, and G.729 is just one of them.

G.729 uses a higher compression ratio than G.711, using by default an 8kbit/s upstream/downstream transmission rate to convey the voice signal. Going back a few years, when internet bandwidths to businesses were more limited than today, it was important to use highly compressed voice signals to maximise the usage of the low rate links. Nowadays, these bandwidth restrictions have been alleviated, so in the majority of cases, there is no reason to select any other voice codec than G.711. But if you need it – we have it! Just let us know and we’ll sort it for you.

The G.729 codec was added following a request from an existing customer. We are always interested to hear your feedback on what features you would like to see supported on the platform. Get in touch if you have an idea

SpeechTEK conference schedule application

Aculab is pleased to be a sponsor of SpeechTEK 2012 this week.  For the event, we decided to provide a little more than just a product demo, so we created an application that conference delegates would find very useful – an automated conference schedule.

The app took just a few hours to develop and incorporates the fundamentals of any IVR system, including the use of TTS.

Below is the call flow and some code snippets from the application.
