The response includes an upload URL for the source audio file. ## OpenAPI ````yaml post /v1/jobs/voice/translate openapi: 3.0.3 info: title: DeepL API Documentation description: >- The DeepL API provides programmatic access to DeepL’s language AI technology. Note: this OpenAPI spec is embedded into our API documentation and has shortened descriptions. termsOfService: https://www.deepl.com/pro-license contact: name: DeepL - Contact us url: https://www.deepl.com/contact-us version: 3.11.0 servers: - url: https://api.deepl.com description: DeepL API Pro - url: https://api-free.deepl.com description: DeepL API Free security: [] tags: - name: beta description: >- Experimental features that are under testing and not yet intended for production use. - name: TranslateText description: >- The text-translation API currently consists of a single endpoint, `translate`, which is described below. - name: TranslateDocuments description: >- The document translation API allows you to translate whole documents and supports the following file types and extensions: * `docx` - Microsoft Word Document * `pptx` - Microsoft PowerPoint Document * `xlsx` - Microsoft Excel Document * `pdf` - Portable Document Format * `htm / html` - HTML Document * `txt` - Plain Text Document * `xlf / xliff` - XLIFF Document, version 2.1 * `srt` - SRT Document * `jpeg` / `jpg` / `png` - Image (currently in beta) - name: RephraseText description: >- The `rephrase` endpoint is used to make corrections and adjustments to texts based on style or tone. - name: CorrectText description: >- The `correct` endpoint fixes spelling and grammar errors without broader rephrasing. Use it when you want a minimal-change correction pass rather than the broader rewriting performed by `rephrase`. - name: ManageMultilingualGlossaries description: >- The *glossary* functions allow you to create, inspect, edit and delete glossaries. Glossaries created with the glossary function can be used in translate requests by specifying the `glossary_id` parameter. A glossary contains (several) dictionaries. A dictionary is a mapping of source phrases to target phrases for a single language pair. If you encounter issues, please let us know at support@DeepL.com. Currently you can create glossaries with any of the languages DeepL supports (with the exception of Thai). The maximum size limit for a glossary is 10 MiB = 10485760 bytes and each source/target text, as well as the name of the glossary, is limited to 1024 UTF-8 bytes. A total of 1000 glossaries are allowed per account. When creating a dictionary with target language `EN`, `PT`, or `ZH`, it's not necessary to specify a variant (e.g. `EN-US`, `EN-GB`, `PT-PT`, `PT-BR`, or `ZH-HANS`). Dictionaries with target language `EN` can be used in translations with either English variant. Similarly `PT`, and `ZH` dictionaries can be used in translations with their corresponding variants. (When you provide the ID of a glossary to a translation, the appropriate dictionary is automatically applied. Currently glossaries can not yet be used with source language detection.) Glossaries created via the DeepL API are now unified with glossaries created via the DeepL website and DeepL apps. Please only use the v3 glossary API in conjunction with multilingual or edited glossaries from the website. - name: ManageGlossaries description: >- Please note that this is the spec for the (old) v2 glossary endpoint. We recommend users switch to the newer v3 glossary endpoints, which support editability and multilinguality. The *glossary* functions allow you to create, inspect, and delete glossaries. Glossaries created with the glossary function can be used in translate requests by specifying the `glossary_id` parameter. If you encounter issues, please let us know at support@DeepL.com. Currently you can create glossaries with any of the languages DeepL supports (with the exception of Thai). - name: MetaInformation description: Information about API usage and value ranges - name: TranslationMemories description: >- The translation memory endpoints allow you to interact with your account's translation memories, used to store and reuse previously created translations. Translation memories can be used in text translation requests by specifying the `translation_memory_id` parameter to denote a specific translation memory and the `translation_memory_threshold` which defines the minimum matching percentage required for a translation memory segment to be applied (recommended to be 75% or higher). - name: VoiceAPI description: >- The Voice API provides real-time voice transcription and translation services. Use a two-step flow: first request a streaming URL via REST, then establish a WebSocket connection for streaming audio and receiving transcriptions. - name: VoiceTranslateJob description: >- **Alpha.** Async voice translation jobs. This API may change without notice. - name: AdminApi description: >- Endpoints for organization administrators to manage API keys and retrieve usage analytics. - name: QualityEvaluation description: >- **Closed alpha.** Evaluate translation quality. Submit source/target segment pairs and retrieve per-segment quality issues categorized by error type and severity, with character spans pointing to where each issue occurs. externalDocs: description: DeepL Pro - Plans and pricing url: https://www.deepl.com/pro#developer paths: /v1/jobs/voice/translate: post: tags: - VoiceTranslateJob summary: Create a voice translation job description: >- Creates an async voice translation job.
