  • Blog Post: I'm back on Speech!

    Mwa, ha, ha, haaa!  Yes, I've (re) joined the Speech at Microsoft team (yay!) where all sorts of speech grooviness is happening, in bigger, better and cooler-than-ever ways (seriously!).  Years ago, when I started this blog, it was to talk about speech APIs, and I'm going to return to those...
  • Blog Post: New Speech Server video on Channel 9

    http://channel9.msdn.com/Showpost.aspx?postid=208891 Albert, Mithun and Dave talk us through some of the great new capabilities of the next version of Speech Server. I worked on the initial version of Speech Server (2004), as well as some of the plumbing of the server and API in the upcoming version...
  • Blog Post: Updating speech samples for beta 2

    When beta 1 shipped, we published this article in MSDN Magazine. We've made some minor tweaks to the API for beta 2, and I figure what better way to illustrate them than to walk through the samples in that article and update them for beta 2. First, the install. I installed two pieces of software...
  • Blog Post: MSDN Magazine article on speech in Vista

    Okay, so I haven't been completely idle: http://msdn.microsoft.com/msdnmag/issues/06/01/speechinWindowsVista/#void (Thanks to Robert Stumberger, Rob Chambers, and the other folks here at Microsoft who helped put this together).

  • Blog Post: WinFX speech API changes in PDC CTP

    Joseph Kilada wrote "Robert, can you give any hints as to whether the WinFX Speech APIs have changed at all in build 5219 (or whatever the PDC build is) compared to Beta 1?" Sometime soon I'll post updates to all the samples I've put in this blog, to make them work with the PDC CTP. The major functionality...
  • Blog Post: Introducing SAPI 5.3

    Vista (a.k.a. Longhorn) has a new version of SAPI: 5.3. SAPI 5.3 is an incremental update to SAPI 5.1. The core mission and architecture are unchanged across all 5.x releases. Among a variety of tweaks, SAPI 5.3 has these overall improvements: Support for W3C grammar and TTS formats (SRGS and...
  • Blog Post: RSS reader using SAPI

    Michael Carbenay's built an RSS client on the .Net runtime 1.1, using COM interop to have SAPI read the feed to you: http://michael.carbenay.info/post-41.htm
  • Blog Post: Speech chess

    Valentin Iliescu's written a WinFX chess application that you can play by speaking to it. Very nice. Thanks Valentin! http://www.valil.com/winfx/
  • Blog Post: Follow-up to speech processing of audio files

    I was asked some questions about my Speech processing of audio files post. Jonathan Tregear asks "Is there a way to get SAPI to convert and recognize any of the WMA audio formats or other compressed formats beyond the Windows OS standard formats?" No, SAPI doesn't work directly with WMA audio formats...
  • Blog Post: Using SAPI with C#

    Want to use SAPI from C#? Take a look at Matt Harrington's article about using SAPI from C# to do speech synthesis . I've done a lot of talking about the upcoming managed speech API in WinFX. But I also get a lot of messages from people who are using SAPI - the current COM-based speech API. I've really...
  • Blog Post: Which SDK gives me access to the System.Speech namespace?

    Josh posted : "I installed the Speech SDK v 5.1 but don't have access to the System.Speech.Synthesis namespace. Do I need to add a reference to it?" You'll need the WinFX SDK for Avalon & Indigo beta 1 RC 1. Here are some instructions for how to get this and install it.
  • Blog Post: Speech processing of audio files

    There are a couple of FAQs I often hear about using speech with audio files: How do I recognize speech that's been recorded to an audio file? How do I write synthesized speech to an audio file? This can be done with SAPI, but judging by the frequency of these FAQs in the newsgroups, it's...
  • Blog Post: Speech recognition of interviews & videos

    Jonathan Tregear recently posted some comments/questions on speech recognition of interviews (in response to a brief discussion I had with Scoble in my Channel 9 interview a couple of months back). I looped in Frank Seide from Microsoft Research Asia to answer these, since he's done a lot of work in...
  • Blog Post: Another speech blogger

    Chris Schindler from the Speech Server team started his blog yesterday ! Today's speech API tidbit: the synthesizer API can also splice audio files into the output stream. Try this: Dim pb As New PromptBuilder pb.AppendAudio( "c:\windows\media\notify.wav" ) pb.AppendText( "You have an...
  • Blog Post: XML from previous speech samples

    The last few samples I've posted have used APIs to construct the input to the speech engines. Under the covers, you can conceptualize these as creating XML files (or at least, they correspond to XML files and can be serialized as such). The PromptBuilder class creates XML in W3C's SSML format . The...
  • Blog Post: Speech synthesis example

    The last couple of posts have dealt with recognition. The other half of speech is synthesis. The System.Speech.Synthesis namespace contains a variety of classes for rendering text to speech. Here's some sample code that uses a PromptBuilder class to utilize a variety of voices. Imports System.Speech...
  • Blog Post: Speech grammars example

    I figured it's about time for another example. A lot of scenarios require the speech recognizer to listen for a constrained set of phrases - a "grammar". The app developer can express this with the W3C's SRGS XML format. The WinFX speech API provides a set of classes for producing an SRGS grammar...
  • Blog Post: Speech sample in VB.NET

    Here's a small sample showing how to use the new Speech API from VB.NET. I'm running VS 2005 beta 2, WinFX SDK, the Avalon & Indigo beta 1 RC , and the speech recogniser that comes with Office 2003. Just create a new VB project and write code like I've pasted below. Remember to add the reference...
