Speechmatics vs Uniphore

Speechmatics' automatic speech recognition API transcribes audio into text in 55+ languages in either real-time streaming or batch mode, with speaker diarization, custom dictionary, translation and summarization options.

Generates a short summary of an audio file in the same API call that transcribes it, as paragraphs or bullets. It is a Speech Intelligence feature enabled by adding a config block to a batch Speech to Text job, not a product bought on its own.

Speechmatics' text-to-speech API generates streaming synthetic English speech from text with sub-150ms latency using four named voices (Sarah, Theo, Megan, Jack), aimed at real-time voice agent use.

Translates a transcript into other languages in the same API call that produces it, for files or live audio. It is a feature switched on inside a Speech to Text request rather than a separate product; the docs file it under Speech to Text and return the translations alongside the transcript.

Speechmatics' voice agent offering provides a real-time conversational speech API - including the Flow WebSocket endpoint that chains speech-to-text, an LLM, text-to-speech and function calling - plus a Python Voice SDK for turn detection and speaker management, and integrations with Vapi, LiveKit and Pipecat.

A locally-executing speech-to-text engine for Mac and Windows laptops that runs on about one CPU core plus the device's neural engine or GPU and roughly 800MB of memory, sending no audio over a network and claiming accuracy within 5% of the cloud API.

A cloud-native enterprise communication recording application that captures voice and screen data, marketed as the capture layer that makes conversation data available to AI. It records uncompressed stereo audio with multi-channel support, includes transcription, and provides customizable policy engines for recording, retention, storage and export alongside MiFID II, Dodd-Frank, PCI DSS and GDPR compliance controls.

A generative-AI conversational intelligence application that analyses 100% of customer conversations to surface trends, sentiment and actionable insights. It automates QA scoring across all calls rather than manual sampling, and surfaces emerging call drivers beyond predefined categories.

An AI agent-assist application that gives contact centre agents in-call support: pre-call intelligence pulled from CRM and past interactions, knowledge assist that delivers contextual answers without manual search, generative conversation summaries with disposition capture, and sentiment detection. A manager dashboard provides live transcription and real-time performance alerts.
