Introducing Kling 2.6 Create Voice: Build Custom Voice Profiles for AI Video Generation

The era of silent AI-generated videos is over. With the release of Kling 2.6, Kuaishou has fundamentally transformed how creators approach AI video production, introducing simultaneous audio-visual generation that eliminates the traditional workflow of generating silent visuals followed by manual dubbing. At the heart of this revolution is Kling 2.6 Create Voice—a powerful endpoint that lets you create reusable voice profiles from your own audio samples, enabling consistent character voices across all your AI video projects.

Now available on WaveSpeedAI, this capability brings professional-grade voice customization to your fingertips with instant API access and predictable pricing.

What is Kling 2.6 Create Voice?

Kling 2.6 Create Voice is a lightweight yet powerful tool designed to extract and store a unique voice profile from an audio sample. Once created, this voice profile becomes a reusable asset that you can reference across multiple Kling 2.6 video generation tasks—no need to re-upload the same reference audio every time you want your characters to speak.

This approach to voice management represents a significant leap forward for content creators. Whether you’re building a consistent brand narrator, developing character-driven content, or producing a series of videos that require the same voice, Kling 2.6 Create Voice provides the foundation for maintaining vocal identity across your entire creative workflow.

Key Features

• One-Time Voice Creation: Upload a clean audio sample once, and receive a voice identifier that works across unlimited video generation runs

• Seamless Integration with Kling 2.6 Video Workflows: The created voice profiles plug directly into Kling 2.6’s text-to-video and image-to-video endpoints that support voice control

• Multi-Voice Support: Reference up to two distinct voices within a single video generation task, enabling dialogue scenes between different characters

• Flexible Audio Input: Works with either public URLs or uploaded audio files, adapting to your existing content pipeline

• Minimal Input Requirements: Just 5-30 seconds of clean, single-speaker audio is all you need to create a compelling voice profile

• Production-Ready API: Built for stable production use with WaveSpeedAI’s infrastructure—no cold starts, consistent performance

Real-World Applications

Brand Content and Marketing

Maintain a consistent brand voice across all your video content. Create a voice profile from your company spokesperson or brand narrator, then use it across product demos, explainer videos, and social media content. Every piece of content sounds cohesive and professionally produced.

Character-Driven Storytelling

For creators producing series content, animations, or narrative-driven projects, voice consistency is crucial. Build voice profiles for each character once, then reference them throughout your production. Your audience will recognize and connect with characters that sound the same across episodes.

Multilingual Content Production

Combined with Kling 2.6’s support for Chinese and English voice generation, Create Voice enables you to develop content strategies that maintain speaker identity across language variants. Create localized content where the core vocal characteristics remain recognizable.

Educational and Training Content

Instructional content benefits enormously from consistent narration. Whether you’re producing a course series, corporate training modules, or educational videos, having the same voice guide learners throughout improves comprehension and engagement.

Social Media and E-Commerce

Scale your content production for platforms like TikTok, Instagram Reels, and product showcases. Once you’ve established a voice that resonates with your audience, replicate it efficiently across hundreds of videos without re-recording or manual dubbing.

Getting Started on WaveSpeedAI

Getting your custom voice profile up and running takes just a few simple steps:

1. Prepare Your Audio Sample: Record or select a clean audio clip between 5-30 seconds. The sample should feature a single speaker with consistent volume, minimal background noise, and no reverb or echo. If you want a specific delivery style—calm narrator, energetic presenter, or dramatic storyteller—choose a sample that clearly demonstrates that style.

2. Call the Create Voice Endpoint: Submit your audio via WaveSpeedAI’s REST API, providing either a URL to your audio file or uploading the file directly.

3. Store Your Voice ID: The API returns a voice identifier that you’ll reference in subsequent video generation calls.

4. Use in Video Generation: When calling Kling 2.6 video endpoints, include your voice ID in the voice_list parameter and use \<\<\<voice_1\>\>\> tags in your prompts to indicate where that voice should speak.

WaveSpeedAI makes this entire workflow seamless with instant API access, no cold starts, and transparent pricing at just $0.035 per voice creation run.

Best Practices for Optimal Results

Audio Quality Matters: The cleaner your reference audio, the better your voice profile. Invest in a quiet recording environment and use a decent microphone. Avoid samples with background music, overlapping voices, or significant room echo.

Match the Intended Use: If your videos will feature energetic product pitches, create your voice profile from an energetic sample. The model captures not just the voice characteristics but also the delivery style present in your reference audio.

Keep Prompts Simple: When writing prompts that reference your custom voice, simpler sentence structures produce more reliable results. For example: The presenter <<<voice_1>>> said, “Welcome to today’s demonstration.”

Respect Consent: Only create voice profiles from audio you own or have explicit permission to use. This is both an ethical best practice and important for avoiding potential legal issues.

The Future of AI Video is Here

Kling 2.6’s simultaneous audio-visual generation capability, combined with custom voice profiles, represents the next evolution in AI content creation. No longer do creators need to piece together silent video clips with separately produced audio tracks. The entire creative process now flows naturally from concept to finished, fully-voiced video.

With WaveSpeedAI, you get the added benefits of enterprise-grade infrastructure: fast inference speeds, zero cold start delays, and predictable per-run pricing that makes it easy to budget for production at any scale.
