Over the years, we’ve covered numerous commercial and free text-to-speech (TTS) offerings for Asterisk® including gTTS, PicoTTS, Amazon’s Polly TTS, IBM TTS, Google TTS, FLITE, and Festival. But SpeechGen’s commercial offering sets it apart both in terms of quality and cost. At a $9.99 price point for 100,000 characters with an easy-to-deploy AGI interface, SpeechGen is almost a perfect fit for Asterisk TTS applications. If you decide to deploy SpeechGen after trying out our demo, we hope you’ll consider using our referral link which helps offset the cost of providing today’s Weather by ZIP Code demo for everyone:

For those who have deployed Incredible PBX, we have a one-minute install script which will put all the pieces in place to use SpeechGen with our News Headlines and Weather by ZIP Code applications. Simply issue the commands below after logging into your server as root. Next, edit speechgen.php and insert your SpeechGen API token and your email address. Then dial 951 or 947 from any extension connected to your PBX to retrieve today’s news headlines or weather forecast for any U.S. zip code.

cd /var/lib/asterisk/agi-bin
wget http://incrediblepbx.com/speechgen.tar.gz
tar zxvf speechgen.tar.gz
rm -f speechgen.tar.gz
./install-speechgen-dialplan.sh
nano -w speechgen.php

Send us your own TTS applications for Asterisk. We’d love to publish them.

  1. Why doesn’t PIAF have dial weather anymore? Where did it go?

    [WM: All current versions of Incredible PBX include the Weather by ZIP Code (947) and News Headlines (951) apps with various free TTS support modules. PIAF 3 is no longer supported. See the Wiki for current releases. ]
