Okko in Speech

The iPhone has proved a game-changer in many regards and speech is no exception. Both Google and Yahoo (with vlingo) have deployed mobile speech applications for the iPhone.
Today I came across another sighting of iPhone speech recognition, Vocalia by Creaceed, employing open-source ASR engine Julius for back-end technology. There is no “push to talk” button but a “shake to retry”, which may prove useful when recognition goes awry. The app supports French, English and German for now and costs €2.99. Dictation is not available at this point, though Julius is certainly capable of it from an architecture point of view.

Other speech and language related iPhone apps:,

• Google Mobile – voice search app
• Vlingo – speech-enables your phone
• Pocket – language learning app
• Voice Dial – speech-enabled dialer
• VoiceThis – speech-enabled dialer
• iSpeak – multi-language translator with synthesized output
• A stuttering aid (not yet available)

Has anyone used these extensively? What is your experience with speech on the iPhone?

Google released a new feature for its Google Mobile iPhone Application yesterday: voice search. Users speak a query and the application returns search results formatted for the iPhone. This is similar to the GOOG411 directory assistance application, which allows users to call a phone number, speak a query and receive information about local listings in voice or SMS formats. However the new application apparently performs recognition locally on the iPhone, meaning it comes bundled with an embedded speech recognition engine.

Aside from GOOG411, during the US presidential Google released Gaudi, a voice indexing technology for video. That makes the iPhone app the third official service the company releases, making use of speech recognition, leaving one guessing when Google’s speech technology becomes available as API, like the Google AJAX Language API for translation and transliteration, rather than bundled as software services. Also, an Android version is probably in the works, one would guess.

All applications are available in US English for now.

In the wake of Google’s release of its Chrome web-browser, speculation on plans for Chrome on other platforms, including Android have drifted ashore. Naturally this has washed aside much recent IE8 news, which, though not a game-changer, is said to introduce many of the much-needed improvements everyone has been looking for from Microsoft.

In light of the browser war raging, a little add-on for Microsoft’s Live Messenger may not stir many waters, even if it promises real-time chat translation between English and 14 other languages. However it is still refreshing to read about technology, which is geared at opening channels of communication, rather than capturing market shares.

What are Google’s plans with Chrome and Android viz. Microsoft IE on Windows Mobile? Will Microsoft leverage its non-browser language services such as translation and speech recognition like Google has been?

I stumbled across some “traditional” news bits this week for speech and language technologies, representing most of the major and a few interesting minor market players . Yahoo is offering some kind of NLP-driven structured search for e-commerce solutions starting next year. A new bundled automatic translation software with automatic learning capabilities was announced by across Systems GmbH and Language Weaver. Loquendo is sponsoring a speech-for-in-car-navigation industry event. Persay, maker of voice authentication software, is shipping solutions securing Planet Payment’s voice-enabled payment processing. Lastly Nuance, continuing its acquisition spree, buys Viecore, a contact-center integration consulting company, indicating a clear focus on strengthening its traditional speech and telephony market position.

Recently I stumbled across and blogged about VoiceGlue, an integration of various GPL-licensed pieces of software, providing full IVR capabilities (including rudimentary speech synthesis but not recognition.) Well, last night, together with Christoph, I finally had a stab at it myself.
Our test setup involved running Fedora 9 virtualized in Mac OS X. Our Fedora installation was missing a few pieces of software beyond the indicated prerequisites, but after about an hour everything was under way.
The trickiest bit proved to be building various modules required for the XML parser (I presume needed later for VoiceGlue-customized DTMF grammar parser.) For some reason CPAN’s console kept conking out on us (claiming inexplicably missing/unbuildable prereqs), so after wrestling with that for some time, we decided to manually build all the modules ourself (hoorah, makefiles).
This worked like a charm, though we hit a snag with the Module::Build perl module, which required C_Support, which in turn required another perl module (ExtUtils-CBuilders), not mentioned in any documentation (scant across the board, though that’s half the fun, isn’t it).
After that, the VoiceGlue installation completed swiftly and all services started running after a minimal bit of configuration.
Next week we’ll be back with some test calls and our first impressions. In the meanwhile we’ll keep our eyes peeled for ASR integration (LumenVox/Sphinx), which will make this a truly valuable stab at open sourcing some of the most expensive carrier-grade technology out there.

Very quiet recently. No big acquisitions, no no speech-tech revolution.

Most interesting: Google announced Mike Cohen (of formerly Nuance) will appear as keynote speaker at SpeechTek in August to reveal Google’s speech technology strategy. Google has already moved into the speech application market with GOOG411, an automatic directory assistance application leveraging business search and Google Maps.
UBC researchers announce speech learning system that doesn’t use traditional data-driven model to learn the sounds of a language. Instead it is said to represent more experience driven learning, much like infants. So far, the system has acquired English and Japanese vowels.
Some product reviews/announcements: a quick history of desktop dictation, uses of TextAloud for the iPhone, and Nuance’s new South African voice “Tessa”.
