Voice AI transforms unstructured audio into actionable business intelligence. Here's how leading companies use speech-to-text technology for competitive advantage in ad targeting and brand protection.
Modern advertising has come a long way from generic, broad-based campaigns. Today, it's all about precision targeting—reaching the right person with the right message at the right time. Voice AI can significantly improve targeting.
The content people consume speaks volumes about their interests. Businesses can discover prevalent themes and subjects by transcribing and analyzing spoken content from sources like podcasts, interviews, or video logs.
For instance, in a podcast episode discussing marathon training, advertisers might have an opportunity to pitch running shoes, energy drinks, or training apps. This kind of contextual relevance ensures that ads are seen, considered, and acted upon.
Imagine serving ads that evolve based on ongoing conversations or discussions. As a podcast progresses from talking about summer fashion to beach holidays, the ads can dynamically shift from showcasing swimsuits to promoting sunscreen lotions or travel deals. This real-time adaptability ensures constant alignment with the audience's immediate context.
Beyond just understanding broad topics, Voice AI can make inferences from the text data, ultimately analyzing the data for user sentiment or even intent. For instance, someone consistently consuming content about eco-friendly living could be targeted with ads about sustainable products or green energy solutions. This hyper-personalization makes the ad experience feel less intrusive and more like a curated recommendation.
For instance, advertisers can serve ads about ergonomic home office furniture or time-tracking software when they read a transcription of voice data and find that certain users viewed a webinar about remote work challenges.
With Speech Understanding models, businesses can extract meaningful insights like sentiment analysis on spoken content. Sentiment analysis helps you understand the context of spoken topics and phrases. For example, if an online video dismisses products that include a chemical called DEET, you won't waste ad spend (or upset your viewers) by serving them content with DEET-based products.
By harnessing the power of Voice AI, advertisers can navigate the complex landscape of modern advertising with greater confidence and effectiveness. When ads resonate, they do more than just sell—they build relationships and foster brand loyalty. In today's saturated market, that's an undeniable competitive advantage.
Brands aren't just commercial entities—they are built on trust, values, and consistent messaging. Today, when virality can be both a boon and a bane, maintaining a brand's image becomes even more critical. A single misalignment can spark widespread criticism or damage a brand's reputation.

Recently, Loop TV leveraged Voice AI to launch its brand safety solution. Loop TV is the premier streaming television company for businesses, serving over 2 billion monthly views for restaurants, office buildings, medical facilities, airports, bars, retail stores, and college campuses.
However, businesses traditionally had little-to-no control over the ads displayed during their streaming services. In a move to protect every brand's integrity, Loop TV launched state-of-the-art ad detection techniques at scale to help businesses prevent inappropriate or competitive advertisements. Loop TV leveraged advanced artificial intelligence models to analyze speech, find unsuitable content, and detect competitive keywords in advertisements streamed on Loop TV streaming channels.
Here's how AI makes it happen:
1. Content Moderation
The expansiveness of the digital world makes it challenging for brands to maintain an eye and ear on every platform. Through transcription and analysis of spoken content, brands can preemptively detect and avoid sensitive or potentially harmful topics.
Suppose a company stands for environmental sustainability. In that case, it would be detrimental for its ads to be mixed with content that downplays climate change. Real-time moderation ensures that brand values remain consistent and uncontroversial.
2. Sentiment Analysis
Beyond mere mentions, understanding the sentiment behind the spoken words is critical. With advanced sentiment analysis, brands can gauge public perception—from glowing praise to constructive criticism or even unwarranted rumors. By proactively addressing voiced concerns, brands can showcase their commitment to customer satisfaction and continuous improvement.
3. Monitoring Brand Mentions
Amidst podcasts, webinars, and video reviews, spoken mentions of a brand can offer invaluable insights. By transcribing these mentions, brands can discover genuine feedback, celebrate endorsements, and quickly respond to misinformation. A rapid response (whether to clarify a misrepresentation or to thank a brand advocate) can make all the difference.
4. PII Redaction
Safeguarding customer information is your legal obligation and a testament to your brand's integrity. This is a critical concern for businesses, as an industry survey found that data privacy is one of the most significant challenges when implementing speech recognition. Utilizing speech-to-text AI to detect and redact Personally Identifiable Information (PII) ensures your brand and customers stay protected online. This feature is part of AssemblyAI's Guardrails, which provide comprehensive protection for your voice AI pipeline.
5. Entity Detection
Brands can better understand their positioning within the broader industry landscape by detecting specific entities mentioned alongside their name. Knowing how frequently your brand is mentioned in the same breath as industry leaders or competitors can help strategize marketing efforts and competitive positioning.
6. Topic Detection
Understanding the broader topics surrounding brand mentions helps your company collect insights into market trends, emerging consumer needs, or areas of potential expansion. If a tech brand frequently finds itself mentioned in conversations about renewable energy, it might hint at a new market segment ready for exploration.
With Voice AI technology, businesses like Loop TV are protecting brands and ultimately unlocking valuable insights within audio data.

Contact Centers
In the world of customer service, every conversation is a data point. Businesses like CallSource analyze call transcripts to improve agent performance, ensure compliance, and understand customer sentiment at scale. By automatically identifying keywords, topics, and customer emotions, contact centers can reduce agent training time, lower handle times, and ultimately increase customer satisfaction. In fact, a recent survey found that 69% of companies cited improved customer service after implementing conversation intelligence.
Healthcare
Administrative burden is a major challenge in healthcare, with research from Nature estimating that operational and administrative activities contributed up to $950 billion in U.S. healthcare costs in 2019. Transcribing patient interactions, clinical notes, and telehealth sessions can free up practitioners to focus on care. For these use cases, AssemblyAI enables covered entities and their business associates subject to HIPAA to use our services to process protected health information (PHI).
AssemblyAI is considered a business associate under HIPAA, and we offer a Business Associate Addendum (BAA) that is required under HIPAA to ensure that AssemblyAI appropriately safeguards PHI. By structuring this data, healthcare organizations can improve documentation accuracy, streamline workflows, and support better patient outcomes.
Implementation Strategy and Best Practices
Strategic speech-to-text implementation requires more than API integration.
Three-phase implementation approach:
- Phase 1 (Weeks 1-2): Define specific business problems and success metrics
- Phase 2 (Weeks 3-4): Select appropriate AI models for your use case
- Phase 3 (Weeks 5-8): Pilot implementation with real-world data testing
Brand safety projects typically require transcription plus content moderation and topic detection models, while ad targeting focuses on sentiment analysis and key phrase extraction.
Next, plan for scale. Your solution should handle fluctuating volumes of audio data without compromising performance or reliability. Companies trust AssemblyAI's industry-leading infrastructure to process millions of hours of audio without outages or issues.
Finally, don't underestimate the importance of accuracy. The quality of your transcription directly impacts the quality of your insights. AssemblyAI's customers consistently report that their users immediately notice a difference in quality and performance when they switch from other speech-to-text providers.
Measuring Business Impact and ROI
To justify and expand your investment in Voice AI, you need to measure its impact. The right metrics depend on your use case, but they should always tie back to a tangible business outcome.
For operational efficiency, track the reduction in manual transcription costs or the decrease in average call handling time. For customer experience, look at Net Promoter Score (NPS) or customer satisfaction (CSAT) scores before and after implementation. Companies often see a direct correlation between higher transcription accuracy and improved customer sentiment.
Business Area | Key Metrics | Expected Improvements |
|---|
Ad Targeting | Click-through rates, conversion rates, campaign ROI | More relevant ad placement, higher engagement rates |
Brand Protection | Brand sentiment scores, crisis response time | Faster issue detection, reduced reputation risks |
Content Operations | Content processing time, accessibility compliance | Faster content turnaround, expanded audience reach |
Customer Service | Call resolution time, customer satisfaction | Reduced handle times, improved first-call resolution |
You can also measure ROI through new revenue opportunities. Are you able to monetize previously inaccessible audio content? Have you created a new AI-powered feature that gives you a competitive edge? By tracking these key performance indicators, you can build a strong business case for the value of speech-to-text technology.
