> For the complete documentation index, see [llms.txt](https://docs.acecentre.org.uk/products/llms.txt). 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. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` 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 what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
