Markdown versions of documentation pages are available by appending `.md` to page URLs; this page is available as [Markdown](https://docs.acecentre.org.uk/products/echo/spelling-and-alphabet.md). # Prediction You can access the prediction settings under Spelling and Alphabet in your app settings. ## Letter Prediction If letter prediction is enabled then the letters will rearrange after every selection to try and put the most likely next letter towards the top of the list. ## Word Prediction If word prediction is enabled then words will be inserted into your list after a letter selection as a 'guess' at what the next word might be. Select the prediction to chose that word. You can also set the number of word suggestions that Echo will give you. ## Language You can change the language that will appear in your list. Echo will use the alphabet from that given language and will predict letters and words based on that language. Note, languages marked as (experinmental) have not been verfied as correct so you may find errors. If you would like to verify these languages for us please get in touch. ## Alphabet order This lets you pick the default order of the alphabet that is used. You can choose to have the letters in alphabetical order or you can have them sorted by frequency order. ## Prompts By default Echo will show and speak a prompt of 'current sentence/word' infront of those selection items. Once you become familiar with Echo you may chose to turn these off so you can hear the text without hearing the prompt. {% embed url="" %} --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.acecentre.org.uk/products/echo/spelling-and-alphabet.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
