Intercom Adds Custom Pronunciation Rules to Fin Voice AI Agent.

Intercom has added pronunciation rules to Fin Voice, its AI-powered voice agent, giving companies precise control over how their brand names and specialized terminology are spoken during customer interactions.

The update addresses a common pain point for businesses using AI voice agents: mispronunciation of brand names, product terms, and industry-specific language. Companies can now define custom pronunciation rules that Fin Voice follows consistently across all voice conversations.

Brian, in a video demonstration announced on LinkedIn, explained that brand name pronunciation directly impacts how customers perceive a company's professionalism and attention to detail. When an AI agent mispronounces a company name or key product term, it can undermine trust and create friction in what should be seamless support experiences.

The pronunciation rules feature lets support teams input phonetic guidance for any term that Fin Voice needs to handle differently from its default text-to-speech processing. This applies not just to brand names but also to technical jargon, acronyms, proper nouns, and industry-specific vocabulary that standard AI models might struggle with.

For companies in specialized fields like healthcare, finance, or technology, this matters significantly. A medical device company can ensure Fin Voice correctly pronounces pharmaceutical terms. A fintech startup can standardize how product features are spoken. The consistency extends across every customer interaction, whether handling simple FAQs or more complex support queries.

This update continues Intercom's pattern of refining Fin Voice capabilities. The company recently added background noise cancellation to handle real-world calling environments, and has been expanding Fin's ability to manage increasingly complex customer scenarios through AI Agent Procedures.

The pronunciation rules are configured through Intercom's admin interface, where support leaders can build and maintain a pronunciation library specific to their business. Changes apply immediately to active Fin Voice deployments without requiring downtime or technical intervention.

Intercom has not disclosed specific technical details about how the pronunciation override system works or whether it uses phonetic notation standards like IPA (International Phonetic Alphabet). The company also has not announced pricing changes related to this feature.

For businesses already using Fin Voice, pronunciation rules represent a straightforward way to eliminate a category of errors that, while small individually, compound into noticeable customer experience issues at scale. For companies evaluating AI voice agents, it signals that vendors are moving beyond basic conversational AI toward features that address the specific identity and communication needs of individual businesses.

The update is available now to Intercom customers using Fin Voice. Full details and setup instructions are available through Intercom's help documentation.
