• Dictation flaw

    From Terry Pinnell@3:633/280.2 to All on Thu Jun 12 07:35:43 2025
    The Windows PC dictation facility is handy. But it has one serious flaw
    IMO. After using the KB shortcut Win+H, the microphone icon stays
    listening for a mere 10 seconds. A pause for anything longer, and you
    have to start it again with a double mouse click on the microphone icon.

    In contrast, no such design limitation on my iPhone. There you just
    toggle it on, dictate for as long as you want, and toggle it off.

    I haven't so far found a way to extend this by any method on the PC.
    Seems a long standing issue. Anyone else had success?

    Metro.Apps have a strange state diagram.

    Unless carefully coded, they go to Suspend State when
    there is a lack of activity.

    This happened to the Groove Music Player, which would
    not play your tune through the speakers, if Groove
    was iconified.

    The Groove Player was eventually fixed, so it could
    kinda do as well as WinAMP.

    But that's the problem for developers, is the state diagram
    for a Metro.App is just silly, and any practical activities
    on the computer need additional coding work to behave properly.
    No such problem with a Win32 application :-)

    And people get these strange stupid ideas in their
    head, they're not willing to ever admit they were wrong.
    To compound their dishonesty about reality, they draw
    the state diagram incorrectly on purpose, not showing
    the actual real life cycle properly. Metro Apps *do*
    fucking well terminate, and the diagram should have a
    stick and ball admitting to that fact. I should not
    have to read the accompanying text to discover
    "oh, heh, heh, by the way if the system is out of
    resources, a suspended Metro.App can be terminated
    by the system". You show that in the diagram, you twit.
    That's why it is called a State Diagram. It shows *all* the
    states and the transitions.

    File a bug in the Feedback Hub, and be quick about it if
    you expect a fix by October drop dead date.

    I don't see this in the MS Apps here?

    Such a pity that the win+h tool, which gives excellent conversion of my
    spoken words, has a limitation on its pause time of a meagre 10 seconds.
    I was hoping to discover someone had found a hack, maybe via the
    registry or PowerShell script, whatever. Even if the present tool could
    flash up a warning or beep after say 8 seconds then I could d-click
    win+h to keep it listening!

    Similar question 7 years ago, with typically useless response from MS: https://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/can-you-leave-windows-10-dictation-on-indefinitely/5d0c574a-5e8b-4fb6-91e1-a5fcb7b99abe

    Could you say something? Or is it in dumb dictation mode, such that
    whatever you say is just taken down (like the typewriter in that rather
    nice TOS episode starring IIRR Teri Garr)?

    Could you create something (and give is a keyboard shortcut) that starts
    the thing every 9 seconds? (Or, if that'd create multiple instances,
    does something like "if not <alreadyrunning> ..." - no, hold on, that
    wouldn't start it if called after 9 seconds as it _would_ still be
    running. I see the problem!)>

    Yes, the ubiquity of 'phone-thinking is continuously irritating. (For
    example, one if not two supermarkets here [UK: Lidl and possibly ASDA]
    no longer issue discount cards to those without a "smart"phone [and
    consequent data contract].)

    The Windows Dictation feature is not a program or an app.
    - it's built into the operating system

    Also of note...Win+H will call the feature with or without the presence
    of a connected microphone. Doing the latter will indicate a microphone
    is not connected.

    If timeout occurs, it can be re-enabled. Design intent for re-enabling,
    iirc was click or touch the microphone icon in the feature's 'bar'.

    I too am impressed with how well it takes my speech and converts it to
    properly spelled text. I have two computers running with two keyboards
    and it's not possible to touch-type on the top keyboard, so this is a
    big help.

    I don't find the time-out a big problem. Of course I'm only dictating
    google search terms most of the time, and they don't take long to say.

    I do plan to transcribe my father's trip diary from his 2-month trip in
    1936, and the timeouts may be a problem there, but otoh, the cursor
    might be in the same place all the time so it will be only another
    click.

    It's an otherwise great too that I wish I'd discovered earlier.

    My gripe is only that the pause allowed is far too short for most
    requirements. In fact it's totally unnecessary IMO. You should be able
    to just switch it off when you want. As with iOS on the iPhone or iPad.
    My 'thinking time' between paragraphs, sentences, phrases - occasionally
    even choosing he right word! - is frequently more than 10s.

    Having to be poised with the mouse to relocate and re-click the mic icon
    (and wait for it to briefly reinitialise) significantly spoils the

    See my reply to ...winston. I'd be interested to hear how you get on
    with your trip diary.

    To help a bit I've just started trying a simple macro I wrote with Macro Express Pro (MEP). Tapping the fairly convenient Numpad key 7 clicks
    once on the mic icon to restart it. Assumes a fixed icon position, of
    course, but so far my choice is not too intrusive.

    (Unfortunately it needs MEP to be executed, otherwise I'd upload it.
    Anyway, easy to reproduce for those with more script know how than me.)

    Even though the timeout isn't exposed in the dictation GUI, you'd think
    there would be a Registry setting that holds the number of seconds, but
    perhaps not. I wonder if the top 2 or 3 Windows tweakers would accept a
    request to find a solution, or perhaps the Nirsoft guy. Failing all of
    that, I've been told that there are 3rd party applications that allow
    better control. People shouldn't have to buy Dragon Naturally Speaking
    to get that basic functionality.

    I have to find the diary first. I know it's in one of two bedrooms.

    But I plan to tell you how it goes when I find it. I have until late
    August.

    I don't really have a smooth workflow to begin with. :-)

    And fwiw, in Adroid, it stops recording after, what, 10 seconds? also.

    Windows 10 has another feature
    Windows Speech Recognition with a different microphone GUI
    Start Menu > Windows Ease of Access > Windows Speech Recognition
    Once run(opened) the shortcut Win+Control+S is available.

    Different GUI for microphone.
    Click the microphone or say Start listening. Can be used in other applications(Word, Notepad, etc.)

    That seems to work well so far (3 instructions), but it dawns on me that
    I usually have the radio or tv on. It's not on now because there is a
    marathon of The Partridge Family. So I won't be able to use it all the
    time, but there are times when it's worth turning the radio off. Tnx
    again.

    Once run(opened) the shortcut Win+Control+S is available.

    Different GUI for microphone.
    Click the microphone or say Start listening. Can be used in other >>applications(Word, Notepad, etc.)

    Hey, thanks, this looks pretty good. I did t he first steps but haven't
    used it yet. While you're in the middle of dictating and giving
    commands, can you still use the keyboard and mouse to do the same
    things?

    It's intersting that for microphone, first choice was headset (of
    course); second choice was desktop microphone, and third was other, in
    some other device. They never mention laptop microphone, or if that is >choice 2 or 3.

    All you need is the right microphone.

    Phased array microphones have the ability to reduce the field of view.

    That's how an Alexa or similar, picks out speech. Part
    of the processing is the multiple microphones on the
    top of the can.

    https://hackaday.com/2023/07/04/3d-audio-imaging-with-a-phased-array-microphone/

    There are some cans with 7 microphones and 15 microphones, available
    to an end user. Rather than the "build your own idea".

    Alexa might be on the order of 5 microphones.

    There was also a beamforming microphone with only 2 microphones
    and it fed the stereo microphone input. At lease one PC audio chip,
    had the driver for that, fitted.

    There was also a device, shaped like a bowl in the kitchen, covered
    with a moderate number of microphones. You place that in a rock concert
    or in a recording session, record the signal from all the microphones,
    then when you get back to the studio, you can play back the recording,
    and "point the virtual beam" and pick out only the drums, only
    the guitar, only the lead singer. And that would help you, if the purpose-positioned microphones failed during the recording, and
    you needed to synthesize a replacement track.

    The speech recognition has a small ability to ignore certain
    input, but microphone technology can make a big difference
    to a result.

    *******

    Another ingredient, is the placement of sound absorbing materials.
    If you were sitting in a chair, the can was pointed at you, what's
    a remaining problem ? The disturbing noise (which is off axis),
    can bounce off the wall behind you, and to the phased array that
    looks like "intended signal". a sound absorbing material placed
    on the wall behind your chair, could improve the SNR.

    And, depending on how serious you are and how worried about how things
    look: just plain cloth material goes a long way, but for real deadening, something with spikes and cavities as in an anechoic chamber. A cheap alternative is eggbox material - the sort of sheets of material eggs are displayed on in retail (in UK, anyway); I've seen countless studio radio stations, private recording studios, etc., with such material on the walls.

    Our egg crates ("flats"), that was mostly an urban legend
    that it works to attenuate sound.

    My friends brothers rock group used to practice
    in the basement of my friends house, and the egg crates
    did nothing to control the noise level. The basement walls
    still resonated.

    The rock group toured about a 250 mile radius from home,
    in an old van, but the money per gig barely paid for gas :-)

    This room, as an example, is claimed to be -20dBa or 20dB
    below human hearing sensitivity. It uses six levels of suspension,
    and the air circulation pipes have sound deadening material
    in the pipe. You don't want to suffocate in all that silence.
    Mom would never hear your rock group practicing in there.

    I don't think there was much claim that it would _absorb_ sound in
    absolute terms (though there was to a minor extent); mainly that it
    would reduce _reflection_ better than a hard wall. Deadening a rock band
    is asking a lot![]

    It is quite disconcerting being in any such chamber. (We had one which
    was really intended to absorb microwave energy, but the design and
    material was quite effective for sound too.)
