If you opt in to Improve Siri and Dictation, your audio input and computer-generated transcripts of your Translate requests, associated with random, rotating, device-generated identifiers, may be stored and reviewed by Apple employees to develop and improve Siri and Dictation, Translate and natural language processing functionality in Apple products and services. Siri Data associated with the random identifier is deleted if you disable Siri and Dictation. Then, go to Settings > Siri & Search and tap to turn off “Listen for ‘Hey Siri’” and “Press Side Button for Siri” (or “Press Home for Siri” if your iPhone has a Home button). You can disable Siri and Dictation by going to Settings > General > Keyboard and tapping to turn off Enable Dictation. You can delete interactions associated with a random identifier and retained for six months or less by going to Settings > Siri & Search > Siri & Dictation History and tapping Delete Siri & Dictation History. To do so, go to Settings > Privacy > Analytics & Improvements, and tap to turn off Improve Siri & Dictation. You can change your setting for Improve Siri and Dictation at any time.
Only Apple employees, subject to strict confidentiality obligations, are able to access audio interactions with Siri and Dictation. Depending on the context of your request, Apple employees may review Siri Data directly relevant to the request, in order to grade the effectiveness of Siri’s response. If one of your Siri or Dictation interactions is selected for review, the request, as well as the response Siri provided, will be analyzed to determine accuracy and to generally improve Siri, Dictation, and natural language processing functionality in Apple products and services. The small subset of requests that have been reviewed may be kept beyond two years, without the random identifier, for ongoing improvement of Siri.
After six months, your request history is dissociated from the random identifier and may be retained for up to two years to help Apple develop and improve Siri, Dictation, and other language processing features like Voice Control. Your request history may include transcripts, audio for users who have opted in to Improve Siri and Dictation, and related request data, such as device specifications, performance statistics, and the approximate location of your device at the time the request was made. Your request history is associated with a random, device-generated identifier for six months. In addition, other Siri Data, such as computer-generated transcriptions of your requests, names of your contacts, apps installed on your devices, and location, is also used to improve Siri. For general text Dictation performed on device (for example, composing messages and notes, but not dictating in a search box), transcripts and audio are not shared with Apple by default, but are shared if you opt in to Improve Siri and Dictation. If you opt in to Improve Siri and Dictation, the audio of your interactions with Siri and Dictation may be stored on Siri servers and reviewed by Apple employees to develop and improve Siri, Dictation, and natural language processing functionality in Apple products and services.
