I am trying to inject a timer between TTS text for audible output. I have the following nodes set up to turn to set a variable and output a msg for audible on or off. I have noticed that it seems the initial execution of the flow seems to truncate the beginning of the audible text ouput. My nodes are:

I have tried to use the following code to pause the output by using a node.send(msg1) and node.send(msg2).

In the flow I have the timer set to 10 seconds and it seems to have no affect. The flow is below. Once again thanks to all who enlighten me.  
Regards

To avoid a concurrency situation where multiple messages arrive in quick succession at the input of the function node - you would be better off having no delay and instead, add a delay node after the function node, set to rate limit mode.

However, if you insist on a delay in the function node - you need to await.

```auto
await new Promise(r => setTimeout(r, 10000));

```
