6. Evaluation Mode Operation
6.2.3.3 Clear
Text
button
The ‘Text Input for TTS’ text box can be cleared at any time using the ‘Clear
Text’ button located directly below it.
6.2.3.4
Insert button and drop-box
The drop-box located next to the Insert button contains a list of all possible
foreign-language characters that might be required when inputting text in
languages other than English. It also contains emoticons and other special
characters, which can be used as inline commands to control the behaviour of
the TTS application when using the EPSON parser. To insert these characters
into the text-box, make a selection and then press the insert button.
6.2.3.5 Speak
button
The Speak button sends an ISC_TTS_SPEAK_REQ message to S1V30xxx,
this message incorporates the contents of the ‘Text input for TTS’ text-box.
Upon receipt of the request message, S1V30xxx should send back an
ISC_TTS_SPEAK_RESP message. If the message displayed is
‘ISC_TTS_SPEAK_RESP : success’ the speak request has been accepted.
Otherwise please refer to the trouble-shooting guide.
Following completion of TTS processing of the text, an
ISC_TTS_SPEAK_READY_IND message will be sent. This message signals
that the TTS application is again ready to receive more input text.
6.2.3.6 Pause
button
This button allows streaming or playback of voice data to be paused at any time.
To unpause the paused process, this button should be clicked again.
Alternatively playback may be continued when in the paused state by clicking
the play button.
It is also possible to begin playback of any other file while in this paused state
using any of the previously described methods (see section 6.3.1.1). In this case,
the currently active process will be stopped and it will no longer be possible to
resume it from its paused state.
6.2.3.7 Stop
button
Clicking the Stop button, while text sent via the Speak button is being
processed and output by the target, will have the effect of sending an
ISC_TTS_STOP_REQ message, which immediately halts TTS processing, and
audio output.
