Process Purpose
The Speech group of processes includes all speech related processes which allow you to manage the use of speech input/output in a project.
The Speech processes group is only available if your subscription includes Speech attributes (a subscription with a "Voice Add-on". See Managing Add-ons). Make sure you check the options "Speech Recognizer ASR" and "Speech Synthesizer TTS" in the "Speech" tab ("Project" menu > "Properties" option > "Speech" tab) to enable the Speech related processes.
See Speech.
The "Speech Prompt Builder"
A prompt is used to pass information or instructions to the operator and indicate that the system is waiting for data input.
The "Speech Prompt Builder" is an MCL-Designer V4 tool that helps you define prompts.
To access it, click 
(always next to a prompt related option).
The "Speech Prompt Builder" window contains a table where you can define the speech out prompt:
Speech Mode column
|
Select the necessary options to define the speech out prompt. Since you can select more than one mode, ensure that they are complementary.
Spelling Mode
|
Words
|
The system will prompt the text as words.
|
Characters

The system will pause for n milliseconds (to create a short/medium/long pause).
|
Pause Medium
|
Pause Long
|
Style
|
Emphasized
|
The system will accentuate the prompt from this point on - it will have a higher volume and a slower speed.
|
Emphasized Reset
|
The system will reset the volume and speed to the values defined in the beginning of the prompt.
|
Volume Higher
|
The system will increase the prompt's volume from this point on (affects the Synthesizer Volume). There is a volume increment on the current value.
|
Volume Lower
|
The system will decrease the prompt's volume from this point on (affects the Synthesizer Volume). There is a volume reduction on the current value.
|
Volume Reset
|
The system will reset the volume to the values defined in the beginning of the prompt.
|
Speed Faster
|
The system will increase the prompt's speed from this point on (affects the Synthesizer Speed). There is a speed increment on the current value.
|
Speed Slower
|
The system will decrease the prompt's speed from this point on (affects the Synthesizer Speed). There is a speed reduction on the current value.
|
Speed Reset
|
The system will reset the speed to the values defined in the beginning of the prompt.
|
Advanced
|
Speed Change

|
Sound File (.wav)
|
The system will play the sound file defined in the "Field" column.
The ".wav" file name + path CANNOT exceed 119 characters.
When naming the .wav file, consider the character length of the path - device's root + manufacturer + MCL's package name (ex: \sdcard\Android\data\com.mcltechnologies.android.client.mot\).
To avoid any issues, make sure the used ".wav" file's frequency is 22050 Hz
|
Language
|
The system will change the prompt language from this point on.
|
|
