The first step: tap Settings, General, Siri. You can also ask Siri to “change the sound of your voice”; when you do, she’ll give you a shortcut to her voice settings.
You can change the gender of Siri’s voice or even give her a new accent.
Want to change the sound of Siri’s voice from female to male, or back to female again? Tap the Siri Voice setting (Settings, General, Siri, Siri Voice), then pick “Male” or “Female” under the Gender heading.
You’ll probably find the Accent setting just above the Gender heading; I say “probably” because not all of Siri’s known languages offer different accents. In English, for example, you can choose between American, Australian, and British accents. If Siri’s speaking French, though, there won’t be any alternate accents to choose from.
Speaking of languages, Siri is fluent in everything from Arabic and Chinese to Russian and Turkish. Just back up to the main Siri screen (under Settings, General, Siri), tap Language, and pick one.
Set Siri’s Voice Feedback setting to “Hands-Free Only” if you want Siri to be quiet most of the time.
By default, Siri will speak aloud at all times, even when your device is switched to silent mode. Want to make a change? Easy.
Just tap Voice Feedback from the main Siri settings screen, You’ve got three settings to choose from: Always, meaning Siri will speak aloud whenever you talk to her; Control with Ring Switch, which will keep Siri quiet whenever the ring switch is set to “silent”; and Hands-Free Only, which means you’ll only hear Siri’s voice when you’re using a headset. If you want Siri to keep quiet most of the time, go for the Hands-Free Only option.
