MeetFree Technology

实时面对面翻译的核心技术The technology behind real-time face-to-face translation

MeetFree 用一条端到端的流式处理链路,把现场语音实时转成双语字幕:语音识别与翻译一体完成,边说边译、低延迟,并可通过云端接口嵌入智能音箱、会议设备等第三方硬件。MeetFree turns live speech into bilingual captions through an end-to-end streaming pipeline: speech recognition and translation run together, sentence by sentence, with low latency — and can be embedded into third-party hardware such as smart speakers and meeting devices via a cloud API.

技术架构Architecture

一条端到端的流式处理链路One end-to-end streaming pipeline

音频从设备麦克风采集,经 WebSocket 实时上行,云端依次完成流式语音识别与实时机器翻译,译文随说随返回。双方无需安装任何东西,一台设备完成全部工作。Audio is captured on the device and streamed over a WebSocket; the cloud runs streaming speech recognition and real-time machine translation in sequence, returning the translation as you speak. Only one device is needed.

01

音频采集Audio capture

设备麦克风采集,前端语音活动检测(VAD)、自动增益与降噪。On-device mic capture with VAD, auto gain and noise handling.

02

实时传输Streaming

WebSocket 双向长连接,音频帧流式上行,断线自动重连。Persistent WebSocket streams audio frames, with auto-reconnect.

03

流式语音识别Streaming ASR

实时语音转文字,结合上下文与术语表,边说边出结果。Real-time speech-to-text using context and glossary.

04

实时翻译与返回Translation & return

识别与翻译一体处理,双语译文逐句返回并显示为字幕。Recognition and translation run together; captions return sentence by sentence.

关键指标Key metrics

为实时对话而生Built for live conversation

以下为面向实时商务对话的设计指标。具体延迟与识别表现会随网络、设备和环境噪音变化,建议在真实场景中实测校准。These are the design targets for live business conversation. Actual latency and recognition vary with network, device and ambient noise; we recommend validating in your own environment.

17
种商务语言,任意两种互译business languages, any pair
秒级Seconds
端到端流式延迟,足以跟上对话end-to-end streaming latency, enough to follow

核心能力Core capabilities

为真实、嘈杂的会谈环境设计Designed for real, noisy meetings

流式语音识别(ASR)Streaming ASR

采用实时流式语音识别模型,结果边说边返回,并结合上下文理解,减少短句误判。Real-time streaming ASR returns results as you speak and uses context to reduce short-utterance errors.

端到端实时翻译End-to-end live translation

语音识别与翻译一体化处理,减少中间环节,降低整体延迟,原文与译文逐句对应。Recognition and translation run together to cut intermediate steps, pairing source and target sentence by sentence.

热词与术语表Hotwords & glossary

可定制行业术语、产品名、专有名词和数字表达,提升专业场景下的识别与翻译准确度。Custom industry terms, product names and numbers improve accuracy in professional settings.

噪音环境优化Noise-robust handling

前端语音活动检测(VAD)、能量阈值过滤、自动增益控制,并提供高噪音环境下的展会模式。On-device VAD, energy thresholds, auto gain and a high-noise exhibition mode.

数字高亮与校验Number highlight & check

会谈中的数字自动高亮,并对可疑数字进行标记,帮助核对价格、数量等关键信息。Numbers are highlighted and suspicious figures flagged to verify prices and quantities.

AI 多语言总结与跨平台AI summary & cross-platform

会谈结束可一键生成多语言 AI 纪要;手机、平板、电脑浏览器均可运行,无需安装。One tap generates multilingual AI summaries; it runs on phones, tablets and desktop browsers without install.

硬件集成方案Hardware integration

把实时翻译能力做进你的设备Bring real-time translation into your device

MeetFree 的实时翻译能力可通过云端实时接口嵌入第三方硬件。硬件厂商无需自建 AI 模型与算力,即可让设备具备多语言实时对话能力。MeetFree's real-time translation can be embedded into third-party hardware via a cloud API. Manufacturers add multilingual live conversation without building their own AI models or compute.

智能音箱 / WiFi 音箱Smart / WiFi speakers

会议室、前台、酒店客房的音箱,直接开口即可跨语言对话。Speakers in meeting rooms, front desks and hotel rooms enable hands-free cross-language talk.

会议设备 / 终端Meeting devices / terminals

多语言会议终端、一体机、前台接待设备,实时显示双语字幕。Multilingual meeting terminals and kiosks display live bilingual captions.

翻译机 / 智能耳机Translators / earbuds

手持翻译机、翻译耳机等可穿戴设备,获得持续升级的翻译能力。Handheld translators and earbuds gain translation that keeps improving.
