Seed Audio 1.0 Overview
What Is Seed Audio 1.0?
Seed Audio 1.0 is an AI audio creation model designed to generate more than isolated speech. It can bring voice, dialogue, sound effects, ambience, timing, and acoustic context together as parts of the same audio scene.
Instead of producing a voice clip first, finding background audio later, and manually assembling every element on a timeline, the model can interpret multiple parts of the intended scene together.
A prompt can describe who is speaking, how the speaker should sound, what is happening around them, when an important line should enter, and what atmosphere the scene should have. This context helps create audio that feels connected rather than assembled from unrelated pieces.
This makes the model useful for narrative audio, short-form video, advertising, game content, podcast-style dialogue, localization, and other projects where sound supports a complete moment. For conventional text-to-speech users, the important difference is creative scope: standalone speech can exist alongside emotion, pacing, environment, and sound cues.

Seed Audio 1.0 Features
Seed Audio 1.0 combines speech generation with broader scene-aware audio creation, working from a shared description of what the listener should hear.
Scene-Level Audio Generation
Generate speech, sound effects, ambience, and other audio elements within one shared creative context, so each layer belongs to the same moment.
Expressive Voice Performance
Shape speech around emotion, prosody, rhythm, pacing, and speaking style while keeping the intended voice recognizable.
Voice Creation from Description or Reference
Shape a voice from a text description, an authorized reference sample, or a combination of both without a separate training workflow for every speaker.
Dialogue Timing Control
Specify when character dialogue should enter. Seed describes current prompt-level timing precision at 100 ms intervals.
Multilingual Audio Creation
Generate across more than 20 languages while carrying voice identity and performance through multilingual production workflows.
Longer Audio Generation
Generate up to two minutes of audio in a single pass and continue the generated content further.
How to Use Seed Audio 1.0
Start by making the creative intent clear, then refine the details that matter most. You do not need to describe every technical audio parameter before generating.
Step 1: Describe the Scene
Write what the listener should hear. Define the speaker, line, tone, and delivery, then add environment, ambience, actions, and important sound cues when needed.
Step 2: Define the Voice
Describe the speaker, or use an authorized reference when supported. Focus on age impression, energy, emotion, speaking style, pace, and role.
Step 3: Add Timing and Context
Describe when dialogue or important moments should occur. Keep the sequence clear instead of stacking unrelated events at once.
Step 4: Generate the Audio
Listen to the complete result and evaluate voice performance, timing, ambience, sound balance, and whether it follows the intended scene.
Step 5: Refine One Problem at a Time
Change one targeted instruction at a time—emotion, timing, or environment—so each new generation is easier to evaluate.
Build Audio Around the Scene, Not Just the Script
Traditional text-to-speech workflows often begin and end with the words that should be spoken. Seed Audio 1.0 allows the prompt to describe the broader listening experience.
Basic Prompt
“The host says the train is arriving.”
Scene-Aware Prompt
VOICE“A calm station announcer speaks over a AMBIENCEspacious railway platform ambience. A distant train ACTIONapproaches as the announcement begins, followed by a SOUND CUEsoft braking sound.”
The second direction adds speaker performance, environment, event order, and sound context. The goal is not to make every prompt long, but to include information that changes what the listener should actually hear.
Use Cases for Seed Audio 1.0
Seed Audio 1.0 is most useful when voice, ambience, sound effects, and timing need to work together as part of the same audio scene.
Video and Short-Form Content
Create narration, dialogue, ambience, and sound cues for videos without producing every audio element separately.
Games and Interactive Stories
Explore character performances, scripted dialogue, environmental sound, and narrative moments within a shared audio scene.
Advertising
Coordinate voice lines, sound cues, ambience, and dialogue timing for short, timing-sensitive advertising content.
Podcast-Style Dialogue
Create spoken scenes with distinct speakers, emotional direction, pacing, and supporting audio context.
Multilingual Content
Create localized audio across supported languages while preserving a consistent voice and creative direction.
Creative Audio Prototyping
Explore how a scene could sound before moving into a larger recording, editing, or sound-design workflow.
When Seed Audio 1.0 Is a Better Fit Than Basic TTS
A simple text-to-speech tool can be enough when the only requirement is to read written text clearly. Seed Audio 1.0 becomes more useful when audio needs additional creative direction.
Basic TTS
neutral reading of written text
Seed Audio 1.0
voice performance, environment, timing, dialogue context, sound effects, multilingual delivery, or the relationship between several audio elements
If all you need is a neutral reading of a sentence, a basic speech generator may be sufficient. If you need sound to communicate a scene, Seed Audio 1.0 offers a broader creative framework.
