Deepgram is a voice AI platform for developers, product teams, and enterprises building applications around spoken conversations. It provides APIs for speech-to-text, text-to-speech, voice agents, and audio intelligence, with support for live audio and prerecorded transcription. Teams can integrate individual speech services or use the unified Voice Agent API to combine recognition, speech generation, and language model orchestration. Enterprise options include custom speech models and deployment choices for different infrastructure and data requirements. ## O que Deepgram pode fazer? ### Streaming and prerecorded transcription Nova speech recognition models transcribe live streams and recorded audio. Available capabilities include speaker diarization, automatic language detection, and formatting for punctuation, dates, and currency. ### Conversation-aware speech recognition Flux STT includes turn detection and interruption handling for real-time voice agents. Flux Multilingual supports multiple languages within a single conversation. ### Conversational speech synthesis Flux TTS generates speech for live conversations, maintaining tone, expression, and continuity across the conversation. ### Unified voice agent orchestration The Voice Agent API combines STT, TTS, and LLM orchestration. It maintains conversation history and supports function calling, prompt updates, and response injections to connect agents with application logic and external systems. ### Transcript enrichment and redaction Speech-to-text add-ons can identify entities such as names, organizations, and locations, redact sensitive personal information, and use keyterm prompting to improve recognition of domain terminology. ### Custom speech models Enterprises can commission speech-to-text models trained on proprietary or novel datasets for specialized vocabulary and edge-case audio scenarios. ## Casos de uso ### Customer service voice agents Build agents that converse with callers, retrieve information from back-office systems, and execute domain-specific actions through application logic. ### Meeting transcription products Use transcripts as the input for meeting-note applications, with speaker labels and readable formatting helping organize conversations. ### Recorded conversation analysis Process archived calls or other recordings to extract named entities and prepare redacted transcripts for downstream analysis. ### Voice capabilities for platforms Embed speech recognition and speech generation into communications or conversational AI platforms that serve other developers and businesses. ## Perguntas frequentes ### How does pricing work?
