In recent months I found myself having to integrate a module of Text To Speech in Italian on Asterisk. I pick up the pages of this blog on my personal experience, trying to explain how quick and comprehensive argument.

Citing literally Wikipedia : The "Text to speech (text to spoken English, often abbreviated to TTS) is the generic name given to a number of technologies speech that is capable of reading with a synthesized human voice, written text, reproducing the sounds corresponding to the text. The TTS software can generally use different voices fictitious male or female, and read the text at different speeds, according to the wishes of the user. "

Of course, the solution based on the Festival, although completely open source, which can not be ruled out given the poor quality of the entries in Italian. After extensive research on the internet I discovered that there are other commercial software solutions with TTS voices in Italian top quality. I will mention some:

• Nuance RealSpeak
• Loquendo TTS

The two solutions produce a given speech impeccable high quality and unlike other speech engines have the advantage of being able to simulate the expressiveness of the voice. Sites listed are available demo of Italian voices, I invite you to try to understand what I mean.

However, both RealSpeak Loquendo that have cost prohibitive (something like figures that are around thousand dollars for each channel competitor), which - personally - I had to continue my research on the internet to find the right balance between quality and price. After a few hours of study of my research, I found the solution to low cost and acceptable quality exists and is called Cepstral Voices .

Cepstral Voices comes from a natural evolution of commercial festival. There are entries for many languages, including just Italian. Moreover, the Italian voice synthesis produces a good quality, although considerably lower than the high-cost solutions mentioned above.

Cepstral, however, has another advantage: it is already integrated with Asterisk using the command Swift :

[cepstral-test]
exten => s,1,Answer()
exten => s,2,Swift("Ciao Mondo")

When I decided to buy a Mac I did it with the conviction to:

• primarily a product of good quality;
• Secondly, performance of all respect;
• an operating system of great quality;
• ability to use the best of three worlds (just mac, linux and windows through virtualization Parallels )

In fact I got all these things, but over time and with use, I have realized that probably - in terms of hardware - Apple has gone a little to save the quality of building components.

In fact, apart from fading in the chassis in which rest the wrists, I had a very strange thing: the white LED that indicates standby (necessary inter alia to know when the mac "resting with eyes open") at some point stopped working. Panic!
