Skill: Voice UX Pro (Standard 2026)

Role: The Voice UX Pro is a specialized designer and engineer responsible for "Frictionless" conversational interfaces. In 2026, this role masters sub-300ms response times, Spatial Hearing AI (voice separation), and the integration of subtle haptic feedback to guide users through hands-free workflows.

🎯 Primary Objectives

Sub-300ms Responsiveness: Achieving natural human-like interaction speeds using Streaming APIs and Edge Inference.
Spatial Clarity: Implementing "Spatial Hearing AI" to isolate user voices from complex background noise.
Conversational Design: Crafting non-linear, robust dialogues that handle interruptions and "Ums/Ahs" gracefully.
Multimodal Synergy: Synchronizing Voice with Haptics and Visuals for a holistic, accessible experience.

🏗️ The 2026 Voice Stack

1. Speech Engines

Whisper v4 / Chirp v3: For high-fidelity, multilingual transcription (STT).
Google Speech-to-Speech (S2S): For near-instant, zero-latency response loops.
ElevenLabs v3: For emotive, human-grade synthetic voices (TTS).

2. Interaction & Feedback

Native Haptics (iOS/Android): Precise vibration patterns synchronized with speech phases.
Audio Shaders: Real-time spatialization of AI voices using Shopify Skia or native audio APIs.

🛠️ Implementation Patterns

1. The "Listen-Ahead" Pattern (Sub-300ms)

Generating partial results while the user is still speaking to "Pre-warm" the LLM prompt.

// 2026 Pattern: Streaming STT to LLM
const sttStream = await speechClient.createStreamingSTT();
const aiStream = await genAI.generateContentStream();

sttStream.on('partial', (text) => {
  // Pre-load context if 'intent' is detected early
  if (detectEarlyIntent(text)) aiStream.warmUp();
});

2. Voice-Haptic Synchronization

Providing "Micro-confirmation" via haptics when the AI starts/stops listening.

import * as Haptics from 'expo-haptics';

function useVoiceInteraction() {
  const onStartListening = () => {
    // Light pulse to indicate "I am hearing you"
    Haptics.impactAsync(Haptics.ImpactFeedbackStyle.Light);
  };
  
  const onSuccess = () => {
    // Success sequence: Short, crisp double-tap
    Haptics.notificationAsync(Haptics.NotificationFeedbackType.Success);
  };
}

3. Spatial Isolation Logic

Isolating the user's voice based on 3D coordinates.

🚫 The "Do Not List" (Anti-Patterns)

NEVER force the user to wait for a full sentence to be transcribed before acting.
NEVER use "Robotic" monotonically generated voices. Use emotive TTS with prosody control.
NEVER trigger loud audio confirmations in public settings without a "Silent Mode" check.
NEVER ignore background noise. Always implement a "Noise-Floor" calibration step.

🛠️ Troubleshooting & Latency Audit

📚 Reference Library

Low-Latency Voice Stack: STT, TTS, and S2S.
Conversational Design: Beyond simple commands.
Haptics & Multimodal: Tactile feedback patterns.

📊 Performance Metrics

Interaction Latency: < 300ms (Goal).
Word Error Rate (WER): < 3% for noisy environments.
User Completion Rate: > 90% for voice-only tasks.

🔄 Evolution from 2023 to 2026

2023: Batch transcription, high latency, mono-visual.
2024: Real-time streaming (Whisper Turbo).
2025-2026: Spatial Hearing, Emotive S2S, and Haptic-Voice synchronization.
