Why Should You Create Videos with Speech in Spanish?

There are many reasons why you might want to create videos with speech in Spanish. If you’re a content creator, sharing videos in this language could help you tap into a new and diverse audience — one with huge engagement potential.

Spanish is the second most spoken language in the world, with over 500 million native speakers across the U.S. and other countries. Vast markets like Mexico, Columbia, Argentina and Spain present untapped opportunities for content creators, influencers and digital entrepreneurs, especially on mobile-driven platforms like TikTok and Instagram Reels.

For all of these reasons, creating a separate Spain-focused channel or localizing your existing videos for Spanish speakers is a smart move if you want to expand globally.

In this article, we’ll show you how to localize your videos with a multilingual video content strategy without significantly increasing your costs or using translation software.

The Challenges of Multilingual Content Creation

Despite the obvious benefits of creating videos with speech in Spanish, the majority of content creators remain locked out of this opportunity due to language, time and cost barriers. This has created a perfect storm of high demand and low supply, making Spanish video localization one of the most lucrative skills you can develop as a content creator.

Here are some of the challenges of multilingual video production that localization using AI tools can help you overcome:

Cost Barriers

Professional video translation can cost hundreds of dollars, while voice acting is even more expensive, making both options unfeasible for most content creators.

Plus, if you want to monetize your content, you’ll need to be able to scale quickly and pivot in response to performance data, brand collaborations or social media trends — yet another reason to keep your budget lean.

Lack of Authenticity

When paying someone else to deliver your content, you’re also losing the personal connection to your audience that makes it engaging to begin with. Through regular uploads, your viewers will get to know your unique voice, inflection and speaking style, and a generic voice actor or translation software just won’t cut it.

Spanish also varies significantly between regions, so a voice actor who speaks Spanish Mexican may struggle to convey ideas to audiences in Argentina or Madrid, limiting the reach of your videos and making them seem less authentic, even with fluent speech in Spanish.

Timing Issues

Traditional translation processes can take 1-2 weeks per video, creating significant delays in publishing schedules.

Content creation is all about timing and consistency, but relying on traditional translation or voice acting services will make it impossible to maintain a consistent schedule that keeps your audience engaged. This could mean you don’t see much return on your investment even though you’re spending hundreds, if not thousands, of dollars to translate your videos.

Cultural Disconnect

Paying voice actors or translators to create videos with speech in Spanish may seem like the best way to create authentic multilingual content, but, these professionals may not understand your specific niche or audience, which could dilute your content or make it seem inappropriate for your intended market.

Could AI Agents Be The Breakthrough Solution?

When it comes to creating videos with speech in Spanish, some creators attempt to learn the language fluently — which typically requires 3-5 years of study and doesn’t solve the issue of accent, pronunciation or cultural inaccuracies.

Creating video content can be challenging and time-consuming enough, and trying to do so in a second language — while admirable — requires a huge amount of mental fortitude and time that many creators just don’t have.

AI agents present a far more efficient and reliable solution. The emergence of high-quality AI voice cloning has completely changed the landscape of multilingual content creation. Now, modern AI tools can generate speech in Spanish in mere minutes while maintaining your authentic voice and delivering the perfect pronunciation and even tweaking content for cultural accuracy.

Argil’s AI clone technology allows you to create a lifelike digital avatar that mirrors your tone, speech and appearance, while speaking over 50 different languages and dialects. We’ll train your clone using a two-minute video of you speaking, and you can use this clone across dozens of videos.

How to Create Videos with Speech in Spanish

To create videos with speech in Spanish using Argil, all you need to do is sign up and upload a short video of yourself speaking so we can generate your AI avatar.

We’ll help you write a script for your video using a text prompt, article or URL, then we’ll turn this script into a short video starring your AI clone. When setting up your video, you’ll just have to select the “Spanish” language option.

Argil’s AI agent will automatically add B-roll, visual transitions, background music and captions (in Spanish, English or another language of your choice). You can then edit your video using our handy drag-and-drop interface to change avatar presentation, video sequence, visuals, audio, captions and camera angles. You can also create videos in different formats and aspect ratios for each platform, with just the click of a button.
