-## Announcements
+## Screen reader announcements
 
 The accessibility module provides announcements by default for the series and point formatters. These can be overridden by passing additional props. See below for more details. Note that the default formats are in English only - any translations would need to be overridden.
 
-- When switching points, announce the point index and x axis then value. 2 (point 2) x 3 (x axis = 3) 8105 (y value) Installation [series name].
-- When focusing on a series, announce series name, sereis position of total and how many points. e.g. Installation, line 1 of 2 with 8 data points.
+- When switching points, announce the point index, _x_-axis, value, and series name. Example: "2, _x_ 3, 8105, Installation", which means it is the 2nd point in the series, with _x_-axis = 3, and a value of 8105 (_y_-axis) in the series "Installation".
+- When focusing on a series, announce the series name, series position of total, and how many points. Example: "Installation, line 1 of 2 with 8 data points."

 Below is an example of a chart with custom `descriptionFormatter` for the series and point. The title and sub title are both specified but hidden. They will still be included in the screen reader announcements to give context to visually impaired users but not be visible on the chart.

 ## Notes
 
-- When focusing on points the tooltip is not announced by screen readers. Instead the point description is read out. If you have key information in the tooltip be sure to include it in the `point.descriptionFormatter`.
