Implement Voice Analytics for Usage Tracking and Insights

Priority

MEDIUM

Context

Voice Analytics tracks voice feature usage, performance metrics, and user engagement. The iOS SDK has comprehensive analytics. The Kotlin SDK is missing this capability.

Current State

• Status: Infrastructure does not exist
• Impact: No insights into voice feature usage
• iOS Has: Complete VoiceAnalytics service

iOS Reference Implementation

• Service: sdk/runanywhere-swift/Sources/RunAnywhere/Analytics/VoiceAnalytics.swift

Implementation Plan

1. Define Common Interfaces (commonMain)

// commonMain/kotlin/com/runanywhere/sdk/analytics/VoiceAnalytics.kt
interface VoiceAnalytics {
    fun trackTranscription(duration: Long, wordCount: Int, accuracy: Float?)
    fun trackTTSSynthesis(textLength: Int, audioDuration: Long)
    fun trackWakeWordDetection(keyword: String, confidence: Float)
    fun trackVoiceConversation(turnCount: Int, duration: Long)
}

class VoiceAnalyticsService(
    private val analyticsService: AnalyticsService
) : VoiceAnalytics {
    
    override fun trackTranscription(duration: Long, wordCount: Int, accuracy: Float?) {
        analyticsService.track(AnalyticsEvent(
            name = "voice.transcription",
            properties = mapOf(
                "duration_ms" to duration,
                "word_count" to wordCount,
                "accuracy" to accuracy
            )
        ))
    }
    
    override fun trackTTSSynthesis(textLength: Int, audioDuration: Long) {
        analyticsService.track(AnalyticsEvent(
            name = "voice.tts_synthesis",
            properties = mapOf(
                "text_length" to textLength,
                "audio_duration_ms" to audioDuration
            )
        ))
    }
    
    override fun trackWakeWordDetection(keyword: String, confidence: Float) {
        analyticsService.track(AnalyticsEvent(
            name = "voice.wake_word",
            properties = mapOf(
                "keyword" to keyword,
                "confidence" to confidence
            )
        ))
    }
    
    override fun trackVoiceConversation(turnCount: Int, duration: Long) {
        analyticsService.track(AnalyticsEvent(
            name = "voice.conversation",
            properties = mapOf(
                "turn_count" to turnCount,
                "duration_ms" to duration
            )
        ))
    }
}

Files to Create/Modify

New Files (commonMain)

• [ ] analytics/VoiceAnalytics.kt
• [ ] analytics/VoiceAnalyticsService.kt

Files to Modify

• [ ] foundation/ServiceContainer.kt (add voice analytics)
• [ ] All voice components (add analytics tracking)

Success Criteria

• [ ] Analytics tracks all voice operations
• [ ] Privacy-compliant (no sensitive data)
• [ ] Integrated into all voice components
