Could you, guys, help me with searching some good TTS (Text-To-Speech) tool for commercial purposes? I checked several tool, but some of them was too expensive ($5000+), such as AT&T, other - low-quality, such as FreeTTS. I need free or low-price (up to $500) application or web service to create wav or mp3 files of English words and phrase in quality suitable for education purposes.
Thanks!
P.S. Large library of ready wav or mp3 files will be also OK.
Seems, I have found service suitable for my purposes - Acapela Box. It's priced based on the number of recorded characters and allows to download voice files in good quality and use them for commercial purposes (except on Radio or TV),
You can use festival http://www.cstr.ed.ac.uk/projects/festival/
The online demo is not for commercial use, but offline version is. You can download compiled version for windows for example from here: http://e-guidedog.sourceforge.net/download.php
To generate a wav file with this compiled version you use it like this:
-unpack festival to C:\ (this version will not work properly if you unpack it somewhere else)
-run C:\festival\src\main\festival.exe
-in console window write this festival command: (utt.save.wave (SayText "This is a test.") "testfile.wav")
You should hear festival saying "this is a test" and your wav file should be saved.
You could also check out yakitome. This is free, has decent voices and you can create/download the files as .wav or mp3. The directions for downloading is under the FAQ's. Hope you didn't waste any money yet!
I found not bad service iSpeech. It has also good pronunciation and it's free for mobile developing.
P.S By the way it's also include ASR

I'm looking for a RESTful Speech to Text service for iOS that will allow me to attach an audio file to a POST request (with an API like AFNetworking), then receive a text response of the translated text. The AT&T API for Speech to Text seems interesting, but there doesn't seem to be any documentation about working with Objective-C.
Are there any such services, free/paid, that would offer the ability to "translate" an audio file into text through a POST request?
How about using the Nexiwave API? I've heard some pretty great stuff about it. http://nexiwave.com/index.php/site-map/119-integrate-voicemail-to-text-in-5-minutes
One option is using Google Chrome API.
Refer to http://mikepultz.com/2011/03/accessing-google-speech-api-chrome-11/
You can recognize using flac(or speex)-encoded audio recording.
I don't know whether it's free or not for commercial product. But you can use it for testing and development purpose.
Try Nexiwave.com. API is here: http://nexiwave.com/index.php/site-map/119-integrate-voicemail-to-text-in-5-minutes
at&t is free/Paid Api and you can make 3 apps for free in at&t you need to post audio and you will get json,Xml in response
https://developer.att.com/apis/speech/docs contain documentation for it.
Also there is another APi http://www.nuance.com/for-individuals/mobile-applications/dragon-dictation/index.htm it's a paid API but as you register you will get API-Key and other key required to make sample application(only for development not for production).
but no one API is accurate as google and siri.
I have made sample application using at&t API,Dragon mobile API and Google.If you have any doubt feel free to ask

I want a text-speech API that works over the web. Google Translate unofficial API doesn't fit because I need to read more than one paragraph and they're limited to 100 chars.
I checked iSpeech, but they require a telephone call to buy credits and since this work maintainers do not speak english and this type of billing/selling is pretty ridiculous, I'm looking forward for another alternative.
Anyone?
EDIT: It must have an pt-BR voice.
I was searching for the exact same thing, I needed pt-BR voice too, and I have just quit using Google TTS because it has got some limitations, bugs (with sentence punctuation endings) and no documentation at all.
I found http://www.voicerss.org/
It works good for me, it's free, simple API and has the Brazilian pt-BR voice we need.
I actually spoke to iSpeech ( http://www.ispeech.org ) the other day, and apparently you can purchase credits directly from the web site (did you click Upgrade?). The reference to having to contact them is regarding higher volume pricing. (I haven't actually upgraded, so I haven't verified this, but that's what they said.)
Alternatives include:
http://ws.neospeech.com
http://acapela-group.com (or http://acapela-box.com)
http://acapela-vaas.com (VaaS means Voice as a Service, and this is a pure web API)
http://www.ivona.com/en/developer/
http://www.voiceforge.com/
https://speechtronic.com
Except for Neospeech, which has a free plan, the others are over my budget... Also, I'm disappointed that Neospeech's API is asynchronous. The API returns a code, whose status you then look up, until you get a url for the result. So it sounds like it's geared towards large amounts of text at a time.

I need to create a pdf file dynamically in vb.net. It needs to contain several images and lines of text.
I am using VS 2003, so whatever solution I use will need to be compatible with the .net 1.1 framework.
The current method I am using is wpcubed, but this requires that all images be converted to bmp format before adding them to the pdf, which can be extremely slow when dealing with a large number of images.
I am aware that there are an awful lot of other 3rd party products that claim to do this, and I have had a search through them. But without registering, downloading, installing and writing code to use each of them in turn, it is very difficult to differentiate between them. So far I have looked into evo pdf and pdfsharp,tallcomponents, dynamicpdf.com but none seem to work with .net 1.1. (Although they don't make this abundantly clear.)
Has anyone else found a method that works and they would recommend (a free one-if possible)?
As this point in time, I would start looking for legacy versions of PDF creation libraries, as it is unlikely any new development will be focused on the 1.x framework. ABCpdf used to support .NET 1.x, but I am not sure you can find an older version.
The PDF specification is open, so you can create your own. the problem is it will takes tons of time. Bearing this in mind, I would look for a PDF library that works, even if it costs money, as the few hundred dollars/euros spent on a component is far cheaper than coding it.
Best sources for open source: SourceForge, CodePlex, Google Code, sometimes Code Project (not as much for complete libraries, however).
There is a version of XSL-FO done for .NET.
Maybe that will do what you want

How did they implement text to speech (TTS)? Is there an open, free API for TTS synthesis? I know about Google Translate, but the license is not clear to me (another issue is that they block a request if it contains a referrer). Any idea?
Majdron,
I'm a lead developer at Quizlet. We're using a combination of our own technology and licensing/purchasing TTS software from several different companies.
There are some open source TTS engines/voices:
http://www.cstr.ed.ac.uk/projects/festival/
http://www.babelfish.org/tts-free.htm
http://espeak.sourceforge.net/
http://freetts.sourceforge.net/docs/index.php
http://mary.dfki.de/
Good luck!
The voices sound exactly the same as http://www.neospeech.com. Also, their list of languages match exactly.
It's not free, you have to license it.
Google has just introduced browser-based access to its speech engine through HTML5.
http://slides.html5rocks.com/#speech-input
To get this page to work, I launched the Chromium browser as follows in Ubuntu:
$ chromium-browser --enable-speech-input
I'm not sure if this works in other operating systems.
Another interesting project is WAMI from MIT:
http://wami.csail.mit.edu
I don't know which specific engine Quizlet are using, but assuming they are using a free service then it might be TTS-API (http://tts-api.com/) which was recently featured on Hacker News.
From what I know is the only "free-to-use" TTS web-API out there. Please comment below if I'm wrong - I'd love to find similar free services. There are a lot of pay only services out there but very very few truly free ones.
Since finding out about TTS-API on HN I've successfully used it in a recent app project. Since the TTS is only a HTTP fetch away I was able to quickly integrate it in both the iOS and Android versions of my app. The service appears to be very quick, so no complaints so far :-)
Nobody gave the right answer. They have their own TTS engine that is connected to a single file located at http://quizlet.com/tts/en.mp3 the file takes arguments with it so the url http://quizlet.com/tts/en.mp3?v=14&b=QXJlYSBvZiBwYXJhbGxlbG9ncmFt&s=m5dx52Q. says "Area of parallelogram" thanks the first base64 string labeled b. I have not discovered what v or s are used for but I know they are essential for making the file speak. I will do more research and get back to this answer.
jj b is correct. The core engine of Quizlet's speech features is Neospeech, and uses Neospeech's VTML (VoiceText [TM] Markup Language) exactly, as far as I can tell.

Many online store share common features, such as payment handling, order tracking, recommendation, shopping cart, CMS, etc.
Are there common opensource / commercial frameworks or packages that developers are using to build these site? Or do many of them building it from scratch?
Services like Shopify look simple to use but I don't want my site to look too right out of a Can and I am worry that there might be limit to the customization I can do.
Can someone point me to a right direction as to what technologies are available? I am looking for a solution that is not restrictive and has plenty of support from the community.
Thanks a lot.
There are plenty of open source solutions out in the wild.
If I were to build an e-shop I would probably take a closer look at Satchmo. Now I'm biased as I like python and postgresql. The system is based on Django, which has a very flexible templating system. But of course it is up to you to make the design.
Check out the features available and the store gallery to see if this is something for you.

here's a blog post I've written about comparing open source ecommerce packages with hosted ones.
We've built SolidShops.com as a hosted ecommerce solution which allows you to build 100% custom and unique stores in html/css.
In the end, it all depends on whether you have budget to go with a hosted solution or if you are willing to install, update, configure, secure, ... an open source package like magento.
oscommerce is vastly used also.
You can also buy a ready-made template for it on template selling websites like template monster.
So for about $200 you can have your whole design/coding done. That is, unles you want custom stuff.
