Key Features

Real-Time Transcription

Streaming speech-to-text with sub-second latency for live captioning, agent assist, and real-time analytics. Words appear on screen as they are spoken, enabling supervisors to follow conversations in progress. Interim results provide instant feedback while final results deliver polished, accurate transcripts. Perfect for live dashboards, accessibility compliance, and agent assist applications that suggest responses in real time.

Real-Time Transcription

50+ Languages

Broad multilingual support with automatic language detection and regional dialect handling for global deployments. The engine recognizes Bulgarian, English, German, French, Spanish, and dozens more languages with native-level accuracy. Automatic language switching handles bilingual conversations without manual configuration. Custom language models can be trained for specific domains to achieve even higher accuracy.

50+ Languages

Speaker Diarization

Automatically identifies and labels different speakers in multi-party conversations, answering the question "who said what and when." Essential for meeting transcription, call analytics, and compliance recording. The system distinguishes between agent and customer voices, assigns consistent speaker labels throughout the conversation, and handles overlapping speech. Output includes timestamped, speaker-attributed text ready for analysis.

Speaker Diarization

Custom Vocabulary

Add industry-specific terms, product names, brand names, and acronyms to boost recognition accuracy for your domain. A pharmaceutical company can add drug names, a tech company can add product codes, and a legal firm can add case-specific terminology. Custom vocabularies are applied per-request, so different business units can use different specialized dictionaries. Pronunciation hints ensure even unusual terms are recognized correctly.

Custom Vocabulary

Smart Punctuation

Automatic punctuation, capitalization, and paragraph formatting produce clean, readable transcripts straight out of the box with no post-processing required. The system understands sentence boundaries, question marks, commas, and even em-dashes from speech patterns alone. Proper nouns and sentence beginnings are automatically capitalized. The result is transcripts that look like they were typed by a professional, ready for review or distribution.

Smart Punctuation

Sentiment Detection

Real-time emotion and sentiment analysis detects frustration, satisfaction, urgency, and other emotional states throughout the conversation. Flag negative sentiment shifts instantly so supervisors can intervene before situations escalate. Aggregate sentiment scores across thousands of calls to identify systemic issues, measure the impact of policy changes, and track customer satisfaction trends over time. Combine with topic detection for deep conversational insights.
