The purpose behind this is so that the user can use a headphone to read the cue output directly to them so no one else hears it, then use a loud speaker for the speaking voice for everyone to hear. Unfortunately this is an advanced feature and is not easy to setup and requires specific hardware, so please bear that in mind. Audio is made up of two separate audio signals, one that is for the 'left' channel and one for the 'right' channel. By default Echo, and everything else, outputs to both channels. You can enable 'Directional Audio' in the audio settings of Echo, you can then chose which channel you want to send each voice through. To seperate the channels you will need an [audio splitter cable](https://www.amazon.co.uk/HosaTech-YMP-137-3-5mm-Stereo-Breakout/dp/B000068O5E/ref=sr_1_7?crid=1GAL99VANVPGO\&dib=eyJ2IjoiMSJ9.PSi88q6Gy1uW3Davw5yiI4cGrsJ7bl2_s94g8_rSM1dPK6znR--Azjmk9wUeqRiXkCKb3W7EAX2IYpdEUL706sVP2H6DKUHB2Vd85mHgHPKKZyVK1n3xx65PPi4Iydkjoxw_Piq6lgT4mx-hCTi6aNnjDqAcvWnCFHC82uM0B3qmw3BFk6xJo8GfurnKJQYgc0vzPwNA6Hz9Z5n569cHRD_B1PsRgCPmzJxIKse6ELTD0C2ZtQIDAxZlqwfhNuKgVD9G0L0dsCiEHJFFKxSkz9sH3Anyb9zEUSayHP3cPvQ.j_HJYUNrK-CVUgzma_tXogfYmzFrvHprokJioVmHPow\&dib_tag=se\&keywords=stereo%2Bbreakout%2Bcable%2B3.5\&qid=1722593708\&sprefix=stereo%2Bbreakout%2Bcable%2Caps%2C102\&sr=8-7\&th=1).

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/audio.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.
