Speech Products

ASR & Transcription
Automatic Speech Recognition converts speech to text. Available for real-time streaming with grammar-based recognition, or batch/offline transcription using statistical language models for free-form audio.

Text-to-Speech (TTS)
Converts text into natural-sounding audio for playback to end users. Supports multiple voices and languages.

Call Progress Analysis (CPA) & Answering Machine Detection (AMD)
Distinguishes machines from live humans, and business from residential lines. Delivers human responders to agents or messages to voicemail with precise timing for outbound campaigns.

Natural Language Understanding (NLU)
Interprets speaker intent using natural language processing. Includes Sentiment Analysis, Call Summarization, Language Detection, and Language Translation capabilities.

Speaker Diarization
Detects and labels different speakers within audio recordings—essential for call center analytics, meeting transcription, and multi-party conversations.

Voice Biometrics
Collect voice prints and authenticate users against real-time audio. Includes anti-fraud measures and deep integration with the ASR stack. See the Voice Biometrics Product Guide for implementation details.
