Speech Blocks

Overview

Speech blocks allow you to incorporate spoken language or text-to-speech functionality into your app. You can use these blocks to make your app speak specific messages, responses, or user inputs aloud, enhancing accessibility and interaction for users who prefer or require auditory cues. By utilizing speech blocks, you enable your app to communicate verbally with users, providing information or instructions in a spoken format.

Text-to-Speech

The "say [text] in [language]" block reads a piece of text aloud in a specified language.

Regular Block

Advanced Block

To access the advanced version of a block:

3. Select Show advanced block.

Inputs

Input	Description
text	Text to generate speech.
language	A parameter that specifies the preferred language for the generated speech. Please refer to IETF BCP 47 for the valid codes.
pitch	A parameter that defines the baseline pitch the speech synthesizer uses when speaking the utterance. Set this property to a value within the range of 0.5 for lower pitch to 2.0 for higher pitch. The default value is 1.0.
rate	A parameter that defines the rate the speech synthesizer uses when speaking the utterance. Lower values correspond to slower speech, and higher values correspond to faster speech.

Note

• The sound plays automatically by the "say [text] in [language]" block. It is not possible to pause or stop the sound.
