Detection Coverage

Eight categories.
Verbal and non-verbal.

Exhaustive coverage across linguistic and acoustic risk surfaces. Every category leverages both speech and biometric signal — never one in isolation.

Sexual

Flag explicit dialogue, erotic audio, and vulgarity. Detect suggestive breathing, moaning, and illicit rhythmic chanting (Hanmai) through acoustic analysis — not just words.

ACOUSTIC + ASR

Prohibited Goods

Real-time identification of audio promoting narcotics, gambling, contraband, and unauthorized transactions through both speech and entity patterns.

TIER · CRITICAL

Hate Speech

Recognize harassment, slander, slurs, and toxic behaviors across 50+ languages — including dialect, slang, and code-switching patterns.

TIER · HIGH

Spam

Detect unauthorized audio advertisements and attempts to divert users via external contact information (Telegram, WhatsApp, WeChat IDs).

ENTITY EXTRACTION

Voiceprint Recognition

Biometric speaker identification to detect ban evasion across accounts. Each enrolled offender remains identifiable across sessions.

BIOMETRIC

Non-Verbal Risks

Detect acoustic violations that ASR alone cannot catch — suggestive breathing, distress sounds, and other illicit non-verbal cues.

ACOUSTIC ONLY

Timbre Analysis

Identify speaker gender, age range, and emotional state through voice timbre — useful for minor-protection and risk profiling.

PROFILING

Cultural Nuance

Context-aware understanding of slang, idioms, and regional expressions — critical for global platforms expanding into new markets.

MULTILINGUAL

Core Engine

Built on hybrid intelligence.
Engineered for global reach.

Audio is the modality with the most edge cases — different languages, accents, acoustic environments, and intent layers. We solve it with a model stack designed for exactly that complexity.

HYBRID MODEL FUSION

Four model architectures. One ensemble decision.

To eliminate the inherent limitations of single-algorithm systems, we integrate a diverse stack of advanced architectures: GAN, TDNN, LSTM, and RNN. This high-efficiency ensemble framework ensures ultra-high precision and robust performance in the most complex acoustic environments.

GAN — synthetic audio detection and adversarial robustness
TDNN — temporal feature extraction for voiceprint identification
LSTM + RNN — sequence modeling for dialog context and intent
Late-fusion ensemble reduces single-model failure modes

INTERNATIONALIZED ASR

Native support for 50+ languages.

Built for your global expansion. Our engine features native support for a vast array of international languages, enabling precise identification of risks in English, Spanish, Arabic, Hindi, Mandarin, Japanese, Korean, and other major global languages. Whether it's localized slang or cross-border interactions, our system keeps your global GTM compliant.

BEYOND ASR

Verbal + non-verbal cues. Voiceprint identity.

We go beyond simple speech-to-text. Our engine provides 360° coverage by recognizing non-verbal risks such as suggestive moaning, erotic breathing, and other acoustic violations. We also offer Voiceprint Recognition and Timbre Analysis, allowing you to identify recurring offenders and manage user identities at a biometric level.

Non-verbal acoustic risk detection — independent of ASR transcript
Voiceprint enrollment lets you track offenders across accounts
Timbre analysis surfaces gender / age signals for compliance
