- NAME
- AbortIO - Abort an IO request
-
- SYNOPSIS
- AbortIO(iORequest)
- A1
-
- FUNCTION
- Aborts a speech IO request. The request may be in the queue
- or currently active.
-
- INPUTS
- iORequest - pointer to the IORequest block of request to abort.
-
- RESULTS
- io_Error field of IORequest set to IOERR_ABORTED
-
- BUGS
-
- SEE ALSO
- narrator.device/BeginIO, exec/io.h
-
- narrator.device/CloseDevice
-
- NAME
- CloseDevice - terminates access to the narrator device
-
- SYNOPSIS
- CloseDevice(iORequest)
- A1
-
- FUNCTION
- Close invalidates the io_Unit and io_Device fields in the
- IORequest, preventing subsequent IO until another OpenDevice.
- CloseDevice also reduces the open count. If the count
- goes to 0 and the expunge bit is set, the device is
- expunged. If the open count goes to zero and the delayed
- expunge bit is not set, CloseDevice sets the expunge bit.
-
- INPUTS
- iORequest- pointer to an IORequest block
-
- RESULTS
- The unit and device pointers of the IORequest block are invalidated.

- narrator.device/CMD_READ narrator.device/CMD_READ
-
- NAME
- CMD_READ - Return the next different mouth shape from an
- associated write.
-
- FUNCTION
- The read command of the narrator device returns mouth
- shapes to the user. The shape returned is guaranteed
- to be differnt from the previously returned shape
- (allowing updating to be done only when something has
- changed). Each read request is associated with a
- write request by the pseudo-unit number assigned by
- the OpenDevice call. Since the first structure in
- the read-mouth IORequest block (IORB) is a narrator
- (write) IORB, this association is easily made by copying
- the narrator IORB into the narrate_rb field fo the read IORB.
- See the .h,i files. If there is no write in progress
- or in the device input queue with the same pseudo-unit
- number as the read request, the read will be
- returned to the user with an error. This is also
- how the user knows that the write request has
- finished and that s/he should not issue any more
- reads. Note that in this case the mouth shapes may
- not be different from previously returned values.
-
- IO REQUEST
- with the narrator_rb structure copied from the
- associated write request except for:
- io_Message - message port for read request
- io_Command - CMD_READ
- io_Error - 0
- width - 0
- height - 0
-
- RESULTS
- IORequest block fields set:
- width - mouth width in millimeters/3.67
- (division done for scaling)
- height - mouth height in millimeters
- shape - compressed form of mouth shapes
- (internal use only)

- NAME
- CMD_RESET - Reset the device to a known state
-
- FUNCTION
- Resets the device as though it has just be initialized.
- Aborts all read/write requests whether active of enqueued.
- Restarts device if it has been stopped.

- NAME
- CMD_START - Restarts the device after CMD_STOP
-
- FUNCTION
- CMD_START restarts the currently active speech (if any)
- and allows queued requests to start.
-
- IO REQUEST
- io_Device set by OpenDevice
- io_Unit set by OpenDevice
- io_Command CMD_START

-
- NAME
- CMD_STOP - Stops the device.
-
- FUNCTION
- CMD_STOP halts the currently active speech (if any) and
- prevents any queued requests from starting.
-
- IO REQUEST
- io_Device set by OpenDevice
- io_Unit set by OpenDevice
- io_Command CMD_STOP

- narrator.device/CMD_WRITE narrator.device/CMD_WRITE
-
- NAME
- CMD_WRITE - Send speech request to the narrator device
-
- FUNCTION
- Performs the speech request. If there is an associated read
- request on the device input queue, write will remove it and
- return an initial mouth shape to the user.
-
- Note: if you are going to be doing reads,
- the mouths parameter must be set to 1.
-
- IO REQUEST
- narrator_rb request block:
- ch_masks - array of audio channel selection masks
- (see audio device documentation for
- description of this field)
- nm_masks - number of audio channel selection masks
- mouths - 0 if no mouths are desired
- 1 if mouths are to be read
- rate - speaking rate
- pitch - pitch
- mode - pitch mode
- 0 if natural mode
- 1 if robotic mode
- sex - 0 if male
- - 1 if female
- io_Message - message port
- io_Command - CMD_WRITE
- io_Data - input string
- io_Length - length of input string
-
- RESULTS
- The function sets the io_Error field of the IORB. The
- io_Actual field is set to the length of the input string
- that was actually processed. If the return code indicates
- a phoneme error (ND_PhonErr), io_Actual is the position in
- the input string where the error occured.

- narrator.device/OpenDevice
-
- NAME
- OpenDevice - open the narrator device.
-
- SYNOPSIS
- error = OpenDevice("narrator.device", 0 , iORequest , 0 );
- D0 A0 D0 A1 D1
-
- FUNCTION
- The OpenDevice routine grants access to the narrator device.
- OpenDevice checks the unit number, and if non-zero, returns
- an error (ND_UnitErr). If this is the first time the driver
- has been opened, OpenDevice will attempt to open the audio
- device and allocate the driver's static buffers. If either
- of these operations fail, an error is returned (see the .h,i
- files for possible error return codes). Next, OpenDevice
- (done for all opens, not just the first one) initializes the
- user's IORequest block (IORB). Default values for sex, rate,
- pitch, pitch mode, sampling frequency, and mouths are set in
- the appropriate fields of the IORB. Note that if users wish
- to use non-default values for these parms, the values must
- be set after the open is done. OpenDevice then assigns a
- pseudo-unit number to the IORB for use in synchronizing read
- and write requests. See the CMD_READ command for more details.
- Finally, OpenDevice stores the device node pointer in the
- IORB and clears the delayed expunge bit.
-
- INPUTS
- deviceName - must be "narrator.device"
- unitNumber - must be 0
- iORequest - a pointer to the user's IORequest block
- ( need not be initialized )
- flags - not used
-
- RESULTS
- error - same as io_Error field of IORB
-
- IORequest block fields set:
- rate - 150 words/minute
- pitch - 110 Hz
- mode - Natural
- sex - Male
- mouths - Off
- sampfreq - 22200
- volume - 64 (max)
