Sleep.ai

Analyzes ambient audio streams captured via device microphone to identify snoring acoustic signatures using machine learning models trained on snoring phoneme patterns. The system processes raw audio in real-time or batch mode, applies noise filtering to isolate snoring frequencies (typically 40-4000 Hz), and classifies detected events with confidence scoring. Detection works without requiring wearable sensors, relying instead on environmental microphone placement near the sleep area.

Aggregates nightly snoring detection events, audio quality metrics, and user-reported sleep data into temporal patterns using time-series analysis and statistical decomposition. The system identifies trends across days/weeks (e.g., Monday snoring worse than Friday), correlates snoring with reported sleep quality scores, and segments sleep into phases based on audio characteristics. Outputs visualizations and statistical summaries showing snoring distribution, variability, and trend direction.

Generates tailored snoring mitigation recommendations by analyzing individual sleep patterns, detected snoring characteristics (frequency, intensity, timing), and user profile data (age, reported triggers, lifestyle factors). The system applies rule-based logic and machine learning scoring to rank interventions (positional therapy, nasal strips, sleep hygiene adjustments, medical referral) by estimated relevance and feasibility. Recommendations are prioritized based on evidence strength and user-specific factors rather than generic one-size-fits-all advice.

Correlates detected snoring events with user-reported sleep quality ratings and optional wearable/device metrics (heart rate variability, movement, sleep stage estimates) to surface relationships between snoring severity and perceived sleep outcomes. Uses statistical correlation and optional machine learning to weight which snoring characteristics (frequency, intensity, timing) most strongly associate with poor sleep quality in individual users. Outputs correlation coefficients, scatter plots, and narrative insights about snoring's impact on this specific user's sleep.

Manages audio recording and snoring detection data across multiple user devices (smartphone, tablet, dedicated sleep monitor) with cloud synchronization and local backup. The system handles device-specific audio codec differences, timestamps across devices with potential clock drift, and ensures data consistency when users switch devices or record from multiple locations. Implements conflict resolution for overlapping recordings and provides fallback to local storage if cloud sync fails.

Processes audio locally on user's device for snoring detection without transmitting raw audio to cloud servers, using on-device machine learning models (TensorFlow Lite, Core ML, or ONNX Runtime). The system extracts acoustic features (spectrograms, MFCCs) locally, runs inference on compressed models, and sends only metadata (snoring event timestamps, confidence scores) to cloud for aggregation and analysis. Raw audio is retained locally with optional encryption and automatic deletion after configurable retention period.

Infers user's sleep position (supine, prone, left lateral, right lateral) during snoring episodes by analyzing audio characteristics and optional device motion data (accelerometer, gyroscope). The system uses acoustic patterns (snoring intensity and frequency vary by position) and motion signatures to estimate position without requiring wearable sensors. Outputs position-tagged snoring events and position-specific snoring statistics (e.g., 'snoring 3x worse in supine position').

Flags snoring patterns that warrant professional medical evaluation (sleep specialist, ENT, primary care) based on severity thresholds, frequency patterns, and user-reported symptoms. The system applies clinical decision rules (e.g., snoring >5 nights/week + daytime sleepiness = possible sleep apnea) and compares user's snoring characteristics to population-level risk profiles. Generates escalation recommendations with reasoning (e.g., 'Your snoring frequency exceeds 80% of users; recommend sleep study evaluation') and provides guidance on next steps (sleep specialist referral, home sleep apnea test, polysomnography).

Tracks changes in snoring patterns following user-initiated interventions (positional therapy, nasal strips, sleep hygiene changes, medical treatments) by comparing pre-intervention and post-intervention snoring metrics. The system allows users to log intervention start dates and types, then computes statistical comparisons (paired t-tests, effect sizes) between baseline and intervention periods. Outputs effectiveness summaries (e.g., 'Positional therapy reduced snoring by 40% over 2 weeks') and confidence intervals around effect estimates.

Generates clinical-grade PDF or web-based reports summarizing snoring patterns, trends, and analysis suitable for sharing with healthcare providers. Reports include snoring frequency/intensity statistics, temporal trends, correlation with sleep quality, position-specific patterns, and escalation risk assessment. Formatting follows clinical report conventions (summary, methods, results, interpretation) and includes disclaimers about limitations (not a diagnosis, not a substitute for professional evaluation). Supports customization (date range, metrics included) and secure sharing (encrypted links, password protection).
