V1.xx is valid for LFH3200, LFH3210, LFH3220, LFH3300, LFH3310

 

V1.17 technical release 2012-05-23

Changed protocol for handling HID-commands to improve stability on fast PC platforms. Now host requests are acknowledged after the request has been processed by the device.

 

V1.15 technical release 2012-02-21

Introduction of a 'SMII-compatibility-mode'. Changing modes is done by pressing F1 + F3 buttons simultaneously for more than five seconds. The F2-Led will light for five seconds afterwards when switching to 'SMII-mode', and accordingly the F3-Led when going back to 'SMIII-mode. A short beep will finally acknowledge the operation. Firmware upgrade and assigning new functionalities to buttons is not possible when in SM2 mode.

Muting time for switch click suppression increased from 40ms to 60ms.

 

V1.14 technical release 2011-08-18

Users of the Dragon Systems Speech Recognition Engine reported delayed output of recognized text in connection with a SpeechMike III.

This issue could be fixed by modifying the switch click suppression.

 

V1.13 technical release 2011-07-14

Fixed a problem under Linux, where the slider versions of SMIII (LFH3210,LFH3220,LFH3310) were not recognized.

Added a third selectable audio sample rate of 16KHz to resolve streaming issues on the Apple platform with 22050Hz and 44100Hz sampling rate.

Changed timing to resolve issues on certain platforms with the Philips proprietary HID-interface (SpeechExec hanging at startup, unreliable operation during dictation).

 

V1.11 technical release 2011-05-25

Because of a changed timing of the HID-command interface, commands were lost under some special circumstances. Doubling the size of the HID-command queue buffer fixed the problem

 

V1.10 technical release 2011-05-24

Several issues have been fixed compared to the previous version:

Some customers reported long boot times with their Dell-PCs when a Speechmike III was connected – fixed

Sometimes recording sensitivity was still too low for the SpeechMagic wizard – upper limit has been increased for an additional +3dB

Device wizard hangs when started right after scanning a barcode – fixed

Some customers reported a startup problem of SpeechExec with an attached Speechmike III - fixed

 

V1.02 technical release 2010-11-10

Nuance reported a problem where the Audio Wizard of SpeechMagic was not able to adjust the recording sensitivity when the input speech was low.

An increase of +6dB of the upper limit of the adjustment range fixed the problem, while still working fine with Dragon.

 

V1.01 technical release 2010-07-20

Fixed problem where muting of button clicks interfered with muting of audio channel initiated by host, which caused problems with Dragon Speech Recognition.

Modified break-points of slider-switch-modes on slider models.

 

V1.00 technical release 2010-06-24
