Example

Byte sequence

Microcontroller

CompactSPEECH 00

Description

Stop current activity (eg playback

recording) and put the CompactSPEECH

in IDLE state

SAS

Say Argumented Sentence

sentence

n arg

Announces sentence number

sentence

n of the currently

selected vocabulary and passes

arg to it sentence

n and

arg are each 1-byte long

When playing is complete the CompactSPEECH sets the

NORMAL

END bit in the status word and activates

the MWRQST signal

If the current vocabulary is undetermined ERR

INVALID is

reported

Example

SAS 00 03

Byte sequence

Microcontroller

1E 00 03

CompactSPEECH 1E 00 03

Description

Announce the first sentence in the

sentence table of the currently selected

vocabulary with ‘‘3’’ as the actual

parameter

Skip Backward

time

length

Skips backward in the current message

time

length units

each of 02s duration and causes message playback to

pause

time

length is a 2-byte parameter that can have

any value up to 320 ie 64s The skip accuracy is 5% This

command is meaningful only in the PLAY state The RES

command must be issued to continue playback

If the beginning of the message is detected during execu-

tion of the SB command execution is terminated the EV

NORMAL

END bit in the status register is set

the

MWRQST signal is activated and the CompactSPEECH

switches to the IDLE state

time

length is greater than 320 ERR

PARAM is set in

the error word

Playback speed does not affect the behavior of this com-

mand

Example

SB 19

Byte sequence

Microcontroller

23 00 19

CompactSPEECH 23 00 19

Description

Skip back five seconds from the current

position in the message being played

SDET

Set Detectors Mask

detectors

mask

Controls the reporting of detection for tones and VOX ac-

cording to the value of the

detectors

mask parameter A

bit set to 1 in the mask enables the reporting of the corre-

sponding detector A bit cleared to 0 disables the reporting

Disabling reporting of a detector does not stop or reset the

detector

The 1-byte

detectors

mask is encoded as follows

Bit 0

Report detection of a busy tone

Bit 1

Report detection of a dial tone

Bits 2 – 4

Reserved Must be cleared to 0

Bit 5

Report detection of no energy (VOX) on the line

(The VOX attributes are specified with the tunable

parameters VOX

TIME

COUNT and VOX

ENERGY

LEVEL)

Bit 6

Report the ending of a detected DTMF

Bit 7

Report the start of a detected DTMF (up to 40 ms

after detection start)

Example

SDET A3

Byte sequence

Microcontroller

10 A3

CompactSPEECH 10 A3

Description

Set reporting of all CompactSPEECH

detectors except for end-of-DTMF

Skip to End of Message

This command is valid only in the PLAY state When in-

voked playback is suspended (as for the PA command)

and a jump to the end of the message is performed Play-

back remains suspended after the jump

Example

Byte sequence

Microcontroller

CompactSPEECH 24

Description

Skip to end of current message

SETD

Set Time and Day

time

and

day

Sets the system time and day as specified by bits 0 – 13 in

the 2-byte

time

and

day parameter The time

and

day

parameter is encoded as follows

Bits 0 – 2

Day of the week (1 through 7)

Bits 3 – 7

Hour of the day (0 through 23)

Bits 8 – 13

Minute of the hour (0 through 59)

Bits 14 – 15

These bits must be set to 1

time

and

day value is not valid ERR

PARAM is set in the error word

Example

SETD 0E09

Byte sequence

Microcontroller

0F 0E 09

CompactSPEECH 0F 0E 09

Description

Set time and day to Monday 130 AM
