Да, Google Veo 3.1 generates videos with high-quality sound built right in. It syncs voices and sound effects to the action perfectly. However, there is a catch: Google’s safety filters often mute the audio if the AI thinks the content is sensitive. Also, using the official Google API is very expensive and slow for most creators.
Stop wasting time with muted videos or complex settings. GlobalGPT gives you easy access to Veo 3.1, Сора 2 Вспышка, Клинг, and Wan all in one spot. Plus, GlobalGPT helps you get clear audio without the annoying “auto-mute” problems you often find on other platforms. For just $10.8 (Pro Plan), you get the best AI video and image tools like Середина путешествия and Flux without the high costs or regional blocks of official sites.
GlobalGPT handles your entire project from start to finish. You can use ChatGPT 5.2 или Клод 4.5 to write your script, then jump straight into Veo 3.1 to make the video. With over 100+ models like Недоумение for research and Sora 2 Flash for visuals, you never have to switch tabs to finish your work.

Does Veo 3.1 Have Sound? Google AI Video Audio Generation Features and 2026 Updates
Yes, Veo 3.1 has native sound. In 2026, Google updated Veo to create audio and video at the same time. This is called Native Audio Synthesis. It means the sound is not just added later; the AI “knows” what the scene should sound like as it draws the frames.
The technical quality is very high. It uses 48kHz high-fidelity sound, which is the industry standard for clear audio. Also, the delay between the picture and the sound is less than 10ms. This makes everything look and sound perfectly timed.
New for 2026, Veo 3.1 supports 4K resolution and 9:16 vertical video. This is perfect for creators making high-quality TikToks or YouTube Shorts with professional sound already included.
| Характеристика | Спецификация Veo 3.1 |
| Audio Sample Rate | 48kHz (High-Fidelity) |
| Sync Latency | <10ms (Real-time Sync) |
| Максимальное разрешение | 4K (Upscaled Ultra HD) |
| Native Aspect Ratio | 16:9 & 9:16 (Vertical Support) |
Key Features: Dialogue, SFX, and Background Music in Veo 3.1
Veo 3.1 can create three main types of audio. The first is Synchronized Dialogue. If you have a person talking, the AI matches their mouth movements to the words perfectly. This is a huge time-saver for animators.
The second feature is Dynamic SFX (Sound Effects). The AI understands physics. If a ball hits a window, Veo 3.1 creates the “crash” sound automatically. It can also do footsteps, rain, or engine noises based on what is happening in the clip.
Lastly, it creates Ambient Soundscapes and Music. You can ask the AI for a “spooky forest” or a “happy pop song” for the background. It will build the mood of the video using its built-in music library.

How to Prompt Sound in Veo 3.1: A Step-by-Step Audio Direction Guide
To get the best sound, you must use Audio Tags in your prompt. For example, if you want a specific voice, type Voice: [Deep and calm]. For background music, use Audio: [Fast jazz]. This tells the AI exactly what to focus on.
You can also control the emotion of the speakers. You can prompt for “whispering,” “shouting,” or “excited.” This makes the Персонажи, созданные с помощью искусственного интеллекта feel much more like real people.
If you are making a long video using the Scene Extension tool (up to 148 seconds), the sound stays consistent. The music won’t suddenly stop or change styles between clips. This helps you tell a professional story without any weird jumps.
| Input Prompt (Text + Tag) | Expected Audio Result |
| A cat meowing. SFX: [Sharp, clear meow] | You will hear a distinct, realistic cat meow synchronized with the cat’s mouth opening. |
| A news anchor speaking. Voice: [Professional, calm tone] | The anchor’s voice will be clear, steady, and sound like a professional broadcast. |
| A busy street. Ambient: [City traffic, distant sirens] | The video will have a background layer of city noise, creating a realistic environment. |
| A romantic dinner. Audio: [Slow jazz music] | A smooth jazz track will play throughout the scene, setting the mood. |
Veo 3.1 vs Sora 2 Flash: Which Model Wins for Sound and Physics?
In 2026, the two biggest rivals are Veo 3.1 and Sora 2 Flash. Veo 3.1 is the winner for social media creators. Its native 9:16 support and 10ms sync latency make it the best for dialogue-heavy TikToks.
Сора 2 Вспышка is better for cinematic movies. It has slightly better “physics,” meaning movements look a bit more like real life. However, Veo 3.1 gives you more control with its “First/Last Frame” features and reference images.

Instead of paying for both official sites, many pros use GlobalGPT to compare these models side-by-side in one window. This way, you can pick the best tool for every specific shot you need.

Troubleshooting: Why Does My Veo 3.1 Video Have No Sound?
The most common reason for a silent video is Safety Filters. Google is very strict. If the AI thinks your video has kids or sensitive themes, it will mute the audio to be safe. If this happens, try changing your prompt to something more neutral.
Another reason is your Model Setting. There is a “Veo 3.1 Fast” model and a “Standard” model. Sometimes the Fast version skips the high-quality audio to save time. Always check your settings before you hit generate.
Lastly, ensure your browser is up to date. Veo 3.1 uses a high-quality AAC audio format. Old browsers or apps might have trouble playing the sound even if it is there.

Часто задаваемые вопросы
Does Google Veo 3.1 generate sound automatically? Yes. Unlike older AI video tools, Veo 3.1 features native audio synthesis. This means the model creates synchronized sound effects, background music, and dialogue at the same time it generates the video frames. You no longer need to use separate AI audio tools for basic soundscapes.
Can I control specific voices or sound effects in Veo 3.1? Absolutely. By using Audio Tags in your text prompt (such as Voice: [Deep male] или SFX: [Thunder]), you can direct the AI to produce specific sounds. You can even specify the emotional tone of the dialogue, such as “whispering” or “shouting,” to match your scene’s mood.
Why is my Veo 3.1 video muted or silent? The most common reason for a silent output is the Google Safety Filter. If the AI detects content that might involve minors, sensitive themes, or copyrighted music, it may automatically mute the audio. Additionally, ensure you are using the “Standard” model rather than the “Fast” version, as the latter sometimes prioritizes speed over high-fidelity audio.
What is the maximum length for a Veo 3.1 video with sound? While base clips are typically shorter, Veo 3.1 supports Scene Extension, allowing you to create continuous videos up to 148 seconds long. The AI maintains audio-visual consistency throughout the extension, ensuring the background music and character voices do not change abruptly.
How can I use Veo 3.1 without a complex Google Vertex AI setup? The easiest way to access Veo 3.1 is through GlobalGPT. It removes all regional restrictions and the need for expensive official API credits. By subscribing to the GlobalGPT Pro Plan ($10.8), you get instant access to Veo 3.1, Sora 2 Flash, and Kling in one unified dashboard, making professional AI video production accessible to everyone.
