Onboard in minutes

Quick setup checklist for MIUI phones

Follow these focused steps to enable the assistant, configure wake behaviour and verify permissions. Use this checklist before building routines or diagnosing recognition issues.

  • Enable the assistant: open Settings → Search for “Assistant” or “Voice” and enable the system assistant. If you can’t find it, check Settings → Apps or Default apps for assistant & voice input options.
  • Set wake method: choose a wake word, dedicated button action or long-press assistant key per your device’s input settings.
  • Grant microphone and notification permissions: Settings → Apps → [Assistant] → Permissions → Microphone, and allow notification access so the assistant can surface reminders and messages.
  • Link accounts and devices: sign into the same Xiaomi account on phone, TV and hubs. For third‑party smart-home devices, enable local device control or the relevant bridge in the Home app.
  • Test basic commands: confirm “What’s my next event?” and “Play [playlist] on [device name]” work before building multi-step routines.

Practical prompts

Prompt library: ready-to-use commands by task

Use these concise prompts on your MIUI phone, TV or smart hub. Replace bracketed items with your device or content names. Keep prompts short for better recognition, or add brief context when you expect follow-ups.

Quick controls

One-shot commands for daily needs.

  • “Check my next meeting”
  • “Play morning playlist on Living Room TV”
  • “Dim bedroom lights to 30%”
  • “Set an alarm for 7 AM”

Routines and chaining

Triggers that start multi-step sequences.

  • “Start my commute routine” — phone navigation + play podcast + turn off home thermostat
  • “Good night” — lock doors, turn off lights, set Do Not Disturb

Context-aware follow-ups

Short conversational handoffs for edits and refinement.

  • User: “Set a timer for 20 minutes.” Follow-up: “Label it Pomodoro.”
  • User: “Remind me to buy milk tomorrow.” Follow-up: “At 10 AM.”
  • “Find the message from Sam” → “Read the latest unread message”

Productivity templates

Voice-first workflows for inbox, calendar and notes.

  • “Triage my inbox: mark newsletters as read and keep flagged from boss” (use sparingly; confirm before bulk actions)
  • “Create a note: project ideas — buy components, contact supplier”
  • “Add event: Project sync, Friday 3 PM, Zoom link”

Accessibility prompts

Voice navigation and assistive commands.

  • “Read unread messages from Sam”
  • “Increase text size in Settings”
  • “Turn on high-contrast mode”

Media control variations

Target specific devices or groups.

  • “On bedroom TV, pause and lower volume to 15%”
  • “Play the news on kitchen speaker and living room TV”
  • “Resume podcast on my headphones”

Privacy & consent phrases

Commands to review or manage voice data and permissions.

  • “Open assistant privacy settings”
  • “Delete my last voice interaction”
  • “Show which apps have microphone access”

Developer test prompts

Edge cases for recognition, interrupts and dictation.

  • Homophone stress: “There/Their/They’re” sequences and long dictation samples
  • Interrupt tests: start a long query then say “Pause” or “Stop” mid-sentence
  • Multi-party: simulate two simultaneous speakers with short, overlapping commands

Protect voice data

Privacy-first configuration and controls

If privacy is a key concern, take these practical steps to reduce what’s stored or shared and to audit voice interactions.

  • Limit cloud processing: choose local speech recognition where available; expect reduced capability for complex queries if cloud features are disabled.
  • Review and delete history: open assistant settings or privacy controls to review voice transcripts and delete interactions tied to your account.
  • Manage permissions: audit microphone and storage permissions for assistant and related apps; remove permissions for apps you don’t trust.
  • Use granular device control: prefer local device names (e.g., “Living Room TV”) for targeted commands and avoid broadcasting broad group names when privacy is needed.

Phone, TV & hubs

Cross-device patterns and handover

Voice experiences vary by device form factor. Use these patterns to make behavior consistent across phone, TV and smart hubs.

  • Same account and network: keep devices on the same Xiaomi account and local network where practical for reliable device discovery.
  • Explicit targeting: include device names in prompts to avoid ambiguity (e.g., “on bedroom TV”).
  • Media handover: when starting media on phone, include the target device to skip manual pairing (for example, “Play jazz on Living Room TV”).
  • Bluetooth handover: for headsets and cars, confirm Bluetooth permissions and disable conflicting assistant apps to ensure a single active assistant.

Fix common failures

Troubleshooting checklist

Use this sequential checklist to diagnose recognition, microphone, and pairing problems.

  • Reboot devices: restart phone, TV or smart hub to clear transient issues.
  • Check microphone access: Settings → Apps → Assistant → Permissions → Microphone. Test with voice memo or recorder to verify capture quality.
  • Reduce background noise: move closer to mic, mute noisy sources, or use a headset with a microphone.
  • Update software: confirm system and assistant app updates are installed on phone and TV.
  • Verify account linkage: sign out and sign back in to your Xiaomi account on affected devices.
  • Reset pairing: remove and re-add Bluetooth headsets or TV from paired devices if media commands don’t reach the target.

For voice UX and prototyping

Developer patterns and testing matrix

A practical set of tests and UX patterns developers can use to validate recognition, context, and error handling across accents and environmental conditions.

  • Create short vs long utterance suites: one-word, short-phrase and paragraph-length inputs to measure intent detection and fallback behavior.
  • Accent and noise matrix: test across multiple speakers with regional accents and recorded background noise at differing levels.
  • Interrupt and guardrails: simulate user interruptions mid-response and confirm graceful cancellation or clarification prompts.
  • Slot confirmation patterns: when collecting critical fields (time, location, names), design a short confirmation step to avoid errors in automation.

FAQ

How do I set up Mi voice assistant and wake word on a MIUI phone?

Open Settings and search for “Assistant” or “Voice.” Enable the assistant and choose your preferred activation method—wake word, assistant button or long-press. Then grant microphone and notification permissions. If your device uses a separate Home or Xiaomi app for voice features, sign in with your Xiaomi account and follow the prompt to link devices.

Can Mi voice assistant operate offline and what functions work without internet?

Some on-device recognition and simple commands (device control, media play/pause, alarms) may work without internet if your phone supports local speech models. Complex queries that require web search, cloud-based language understanding or third‑party services typically need connectivity. Check your assistant settings for an option to prefer on-device or cloud processing.

How do I connect and control smart-home devices from my phone and TV reliably?

Sign into the same Xiaomi account on all devices, enable device discovery in your Home or device-management app, and assign clear device names (e.g., “Kitchen Light,” “Living Room TV”). Use explicit device-targeting in prompts and prefer local network control (LAN) or official bridges where possible to reduce latency and improve reliability.

What privacy controls let me review, export, or delete voice interactions?

Open assistant privacy settings to review recorded interactions and transcripts. Many assistant settings include options to delete individual voice entries or clear history for a time range. For export and detailed controls, check account-level privacy or data settings tied to your Xiaomi account—use them to limit cloud storage or remove saved voice data.

How do I create multi-step routines (morning/evening/commute) with voice triggers?

Create a routine inside your Assistant or Home app by defining a trigger phrase and a sequence of actions (lighting, thermostat, media, navigation). Start simple—two or three actions—and test stability. Use explicit device names and confirmations for critical steps (e.g., “Start commute routine” should confirm navigation destination).

Why does the assistant sometimes mishear me and how can I improve recognition accuracy?

Common causes include background noise, low microphone sensitivity, ambiguous phrasing, or mismatched language/region settings. Improve accuracy by speaking clearly, reducing ambient noise, using a close-range microphone or headset, and checking language and regional settings match your dialect. Short, specific commands usually perform better than long, complex sentences.

How can developers test voice UX across accents, background noise, and short/long commands?

Build a testing matrix that combines speaker accents, noise environments, and utterance lengths. Include homophone tests, interruption handling, long-form dictation, and device-targeting prompts. Log recognition transcripts and compare intent mapping against expectations to find failure modes and design fallback prompts.

What troubleshooting steps fix microphone, permission, or pairing issues?

Restart devices, confirm microphone permission for the assistant, test the microphone with a recorder, update system and app software, ensure Bluetooth pairings are healthy (remove and re-pair if needed), and verify account sign-in and network connectivity.

Does voice control work consistently across multiple devices owned by one user and how is handover handled?

Consistency improves when devices share the same account and local network. Explicit device-targeting in prompts reduces ambiguity. Handover behavior varies by device and OS: prefer explicit commands (“Play on Living Room TV”) for reliable results and confirm device availability in the Home or device-management app.

Which languages and regional settings lead to the best recognition and how do I change them?

Recognition is best when your assistant language and phone region match the speaker’s dialect. Change language and region in Settings → System or Assistant language options. If your accent is supported, select the closest regional variant for improved results.
