How Do I Speak a Notebook and Control the Speech Rate in My Pathfinder?
How to Speak a Notebook:
There may be times when you will want to speak a Notebook. There are three insertable Tools that will allow you to speak your Notebook.
The SPEAK ALL Tool:

Store and use SPEAK ALL when you want to speak any open Notebook For example, open a Notebook and then activate the key or icon sequence where you stored SPEAK ALL. This will speak the entire Notebook at once.
The SPEAK NOTEBOOK Tool:

Store and use SPEAK NOTEBOOK when you want to speak a specific Notebook. When you insert and store this tool on your overlay, you must also store with it the name of the Notebook you want to speak.
The SPEAK NEXT SENTENCE Tool:
Store and use SPEAK NEXT SENTENCE when you want to speak a Notebook one sentence at a time. This helps to control the speed at which the Notebook is spoken and allows you to stop between sentences to answer questions if needed. SPEAK NEXT SENTENCE must be selected everytime you want to continue speaking the Notebook.
You can also store the entire NOTEBOOK MENU under an icon sequence on your overlay if you wish.

The Notebook Speech Rate Option
We have found that the regular speech rate is often too fast for people
who are listening to long pieces of spoken text. The Notebook Speech
Rate option allows you to select a speech rate that is different from your
normal conversational speech rate. A slower speech rate helps people to
follow along better.
When you select a Notebook speech rate, the Pathfinder will use that
speech rate with any Notebook you want to speak. We suggest you
select some different speech rates and then have someone listen to each
rate for a few minutes so you can decide which rate will be best for your
listeners.
To Select a Notebook Speech Rate:
1. Open the NOTEBOOK Menu.
2. Activate MORE ITEMS.
3. Activate option #4: Notebook Speech Rate.
4. Practice with some different rates before you select a final one.
