什麼是語音服務?What are the Speech Services?

Azure 語音服務會將語音轉文字、文字轉語音及語音翻譯整合至單一 Azure 訂用帳戶。Azure Speech Services are the unification of speech-to-text, text-to-speech, and speech-translation into a single Azure subscription. 藉由語音 SDK語音裝置 SDKREST API,可輕易地透過語音來啟用您的應用程式、工具和裝置。It's easy to speech enable your applications, tools, and devices with the Speech SDK, Speech Devices SDK, or REST APIs.


語音服務已取代 Bing 語音 API、翻譯工具語音和自訂語音。Speech Services have replaced Bing Speech API, Translator Speech, and Custom Speech. 如需移轉說明,請參閱 [操作指南] > [移轉] 。See How-to guides > Migration for migration instructions.

服務Service 功能Feature 說明Description SDKSDK RESTREST
語音轉文字Speech-to-Text 語音轉文字Speech-to-text 語音轉文字會即時地將音訊串流轉譯成文字,以便您的應用程式、工具或裝置使用或顯示。Speech-to-text transcribes audio streams to text in real time that your applications, tools, or devices can consume or display. 若搭配 Language Understanding (LUIS) 使用語音轉文字,即可從轉譯的語音衍生使用者意圖,以及根據語音命令執行動作。Use speech-to-text with Language Understanding (LUIS) to derive user intents from transcribed speech and act on voice commands. Yes Yes
批次轉譯Batch Transcription 批次轉譯可讓您非同步地對大量資料進行語音轉文字的轉譯。Batch transcription enables asynchronous speech-to-text transcription of large volumes of data. 這是以 REST 為基礎的服務,其在自訂和模型管理上使用相同端點。This is a REST-based service, which uses same endpoint as customization and model management. No Yes

自訂語音體驗Customize your speech experience

Azure 語音服務可順利地與內建模型搭配使用,不過,您可以進一步自訂及調整體驗,以搭配您的產品或環境。Azure Speech Services works well with built-in models, however, you may want to further customize and tune the experience for your product or environment. 從原音模型調整到專屬於自身品牌的獨特聲音音調,都是自訂選項的範圍。Customization options range from acoustic model tuning to unique voice fonts for your brand. 建立自訂模型之後,您可以將其與任一 Azure 語音服務搭配使用。After you've built a custom model, you can use it with any of the Azure Speech Services.

語音服務Speech Service 模型Model 說明Description
語音轉文字Speech-to-Text 原音模型Acoustic model 針對用於特定環境 (例如汽車或工廠) 的應用程式、工具或裝置建立自訂原音模型,而這每一個的錄音條件都較特殊。Create a custom acoustic model for applications, tools, or devices that are used in particular environments like in a car or on a factory floor, each with specific recording conditions. 例如,帶有口音的語音、特定背景雜音或使用特定麥克風來錄音。Examples include accented speech, specific background noises, or using a specific microphone for recording.
語言模型Language model 建立自訂語言模型來提升特定領域的詞彙和文法轉譯,例如醫療術語或 IT 專業術語。Create a custom language model to improve transcription of field-specific vocabulary and grammar, such as medical terminology, or IT jargon.
發音模型Pronunciation model 使用自訂發音模型,您可以定義語音形式和顯示字組或字詞。With a custom pronunciation model, you can define the phonetic form and display of a word or term. 它可用於處理自訂的字詞,如產品名稱或縮略字。It's useful for handling customized terms, such as product names or acronyms. 您只需要有發音檔 - 簡單的 .txt 檔。All you need to get started is a pronunciation file -- a simple .txt file.
文字轉語音Text-to-Speech 聲音音調Voice font 自訂聲音音調可讓您為自己的品牌建立可辨識的獨特聲音。Custom voice fonts allow you to create a recognizable, one-of-a-kind voice for your brand. 只需少量資料即可開始建立。It only takes a small amount of data to get started. 提供的資料愈多,您的聲音音調聽起來就愈自然且愈像真人。The more data that you provide, the more natural and human-like your voice font will sound.
