# text to speech

This block is part of the [`state ui`](https://docs.rual.nl/block-types/state%20ui) group and was last modified in core [`v10.4.28`](https://docs.rual.nl/core-versions/100428).

- text required `value` The text it should speak

- pitch `number` Amount of pitch (0-2) • Min: 0 • Max: 2

A typical wiring for [text to speech](https://docs.rual.nl/block-types/state%20ui/state_speech_synthesis_utterance): a [function trigger](https://docs.rual.nl/block-types/globals/trigger_custom_function) starts the flow; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `voice` pin; [value](https://docs.rual.nl/block-types/value/value_default) feeds the `text` pin; the `flow` out pin feeds [debug](https://docs.rual.nl/block-types/state%20ui/state_debug).
