How Accurate Is Spotwise in Different Languages? A Quick Look at Multilingual Ad Monitoring

Introduction: Audio Monitoring Without Language Barriers

When it comes to broadcast advertising, language shouldn't be a limitation - and with Spotwise, it isn’t.

Whether you’re monitoring ads in German, Latvian, Spanish, or English, Spotwise is built to understand and accurately process a growing number of languages. In this post, we’ll break down how Spotwise performs across different languages and why its multilingual capabilities are a serious advantage for broadcasters, media buyers, and advertisers.

Multilingual by Design

Spotwise isn’t just capable of detecting English ads. From day one, it was designed to support a wide range of languages - including many that are underserved in traditional ad monitoring platforms.

Our AI models continue to learn from new markets and adapt to regional speech patterns, idioms, and accents. That means whether you're tracking a campaign in French-speaking Belgium or Lithuanian radio, Spotwise adapts without requiring manual adjustments.

Accuracy Where It Matters Most

In core markets and widely spoken languages, Spotwise delivers over 95% transcription accuracy. That includes English, German, Spanish, and French - all of which are supported at enterprise-grade precision.

For less common or regional languages, Spotwise still performs well, with accuracy averaging above 90%, consistently outperforming legacy tools in comparative tests. This level of precision allows teams to:

• Trust the data they're seeing
• Monitor small-market campaigns reliably
• Get real-time alerts even in niche languages

In the rare cases where Spotwise does make an error, it’s most often due to unfamiliar brand names being interpreted incorrectly. However, once such a brand is identified and corrected, the model retains that correction going forward - meaning the mistake won’t repeat itself.

Sample Accuracy by Language :

Language and Approx. Accuracy (%)

• English 97%
• German 96%
• Spanish 95%
• French 95%
• Latvian 92%
• Lithuanian 91%
• Estonian 91%
• Polish 90%
• Czech 90%

Note: Accuracy rates are based on internal Spotwise benchmark testing and are continuously improving as models evolve.

Always Learning, Always Expanding

Spotwise’s language coverage is constantly growing. As more campaigns are logged and processed in new markets, our models refine their accuracy further. This means the tool doesn’t just work in your market - it gets better over time.

For international agencies or radio groups operating across borders, this adaptability offers unmatched scale and ease.

Why It Matters

When you rely on ad analytics, the accuracy of what’s captured - and how it’s interpreted - directly affects decisions.

With Spotwise, you’re not just getting keyword flags or vague summaries. You’re getting full transcripts, searchable audio feeds, and real-time campaign intelligence in whatever language your market demands.

Whether your station broadcasts in Dutch or your advertisers speak Estonian - Spotwise is built to listen.

Final Note: Local Doesn’t Mean Limited

Spotwise proves that powerful radio ad analytics aren’t reserved for English-speaking countries. By maintaining high accuracy across languages - and actively improving its models - it gives every team, in every region, a reason to track their airwaves with confidence.
