Integrate Audio Generation

集成音频生成

PREREQUISITE: Run
+check-compatibility
first. Run
+fetch-api-reference
to load the latest API reference before integrating. Requires
+setup-api-key
for API credentials. Requires
+integrate-uploads
for local audio/video files.

Help users add Runway audio generation to their server-side code.

前置条件： 先运行
+check-compatibility
。集成前请运行
+fetch-api-reference
加载最新的API参考文档。需要运行
+setup-api-key
配置API凭证。处理本地音频/视频文件需要先配置
+integrate-uploads
。

帮助用户在服务端代码中接入Runway音频生成能力。

Text-to-Speech

文本转语音

Generate speech from text using the ElevenLabs multilingual model.

使用ElevenLabs多语言模型从文本生成语音。

Node.js SDK

javascript

import RunwayML from '@runwayml/sdk';

const client = new RunwayML();

const task = await client.textToSpeech.create({
  model: 'eleven_multilingual_v2',
  text: 'Hello, welcome to our application!',
  voiceId: 'voice_id_here'  // See voice listing endpoint
}).waitForTaskOutput();

const audioUrl = task.output[0];

javascript

import RunwayML from '@runwayml/sdk';

const client = new RunwayML();

const task = await client.textToSpeech.create({
  model: 'eleven_multilingual_v2',
  text: 'Hello, welcome to our application!',
  voiceId: 'voice_id_here'  // See voice listing endpoint
}).waitForTaskOutput();

const audioUrl = task.output[0];

Python SDK

python

from runwayml import RunwayML

client = RunwayML()

task = client.text_to_speech.create(
    model='eleven_multilingual_v2',
    text='Hello, welcome to our application!',
    voice_id='voice_id_here'
).wait_for_task_output()

audio_url = task.output[0]

python

from runwayml import RunwayML

client = RunwayML()

task = client.text_to_speech.create(
    model='eleven_multilingual_v2',
    text='Hello, welcome to our application!',
    voice_id='voice_id_here'
).wait_for_task_output()

audio_url = task.output[0]

Sound Effects

音效生成

Generate sound effects from text descriptions.

javascript

const task = await client.soundEffect.create({
  model: 'eleven_text_to_sound_v2',
  promptText: 'Thunder rolling across a stormy sky'
}).waitForTaskOutput();

python

task = client.sound_effect.create(
    model='eleven_text_to_sound_v2',
    prompt_text='Thunder rolling across a stormy sky'
).wait_for_task_output()

根据文本描述生成音效。

javascript

const task = await client.soundEffect.create({
  model: 'eleven_text_to_sound_v2',
  promptText: 'Thunder rolling across a stormy sky'
}).waitForTaskOutput();

python

task = client.sound_effect.create(
    model='eleven_text_to_sound_v2',
    prompt_text='Thunder rolling across a stormy sky'
).wait_for_task_output()

Voice Isolation

人声分离

Extract voice from audio with background noise.

javascript

// If using a local file, upload first
const upload = await client.uploads.createEphemeral(
  fs.createReadStream('/path/to/noisy-audio.mp3')
);

const task = await client.voiceIsolation.create({
  model: 'eleven_voice_isolation',
  audio: upload.runwayUri
}).waitForTaskOutput();

从带有背景噪音的音频中提取人声。

javascript

// If using a local file, upload first
const upload = await client.uploads.createEphemeral(
  fs.createReadStream('/path/to/noisy-audio.mp3')
);

const task = await client.voiceIsolation.create({
  model: 'eleven_voice_isolation',
  audio: upload.runwayUri
}).waitForTaskOutput();

Voice Dubbing

配音

Dub audio/video into other languages.

javascript

const task = await client.voiceDubbing.create({
  model: 'eleven_voice_dubbing',
  audio: 'https://example.com/speech.mp3',
  targetLanguage: 'es'  // Spanish
}).waitForTaskOutput();

将音频/视频配音为其他语言。

javascript

const task = await client.voiceDubbing.create({
  model: 'eleven_voice_dubbing',
  audio: 'https://example.com/speech.mp3',
  targetLanguage: 'es'  // Spanish
}).waitForTaskOutput();

Speech-to-Speech

语音转语音

Convert one voice to another.

javascript

const task = await client.speechToSpeech.create({
  model: 'eleven_multilingual_sts_v2',
  audio: 'https://example.com/original-speech.mp3',
  voiceId: 'target_voice_id'
}).waitForTaskOutput();

将一种声音转换为另一种声音。

javascript

const task = await client.speechToSpeech.create({
  model: 'eleven_multilingual_sts_v2',
  audio: 'https://example.com/original-speech.mp3',
  voiceId: 'target_voice_id'
}).waitForTaskOutput();

Tips

注意事项

Output URLs expire in 24-48 hours. Download audio files to your own storage.
For local audio files (voice isolation, dubbing, speech-to-speech), upload via
```
+integrate-uploads
```
first.
Voice IDs can be listed via the voices endpoint — see
```
+api-reference
```
for details.
Text-to-speech cost scales with text length: 1 credit per 50 characters.

输出链接有效期为24-48小时。 请将音频文件下载到您自己的存储中。
如需处理本地音频文件（人声分离、配音、语音转语音），请先通过
```
+integrate-uploads
```
上传。
Voice ID可通过voices端点查询 — 详情请参考
```
+api-reference
```
。
文本转语音费用随文本长度递增：每50个字符消耗1积分。
