WellSaid Expands AI Voice Offering

WellSaid has upgraded the developer application programming interface for its artificial intelligence voice with greater controls and a new pricing structure to help engineering teams build voice experiences faster, with full programmatic control and costs reduced by up to 50 percent.

The company also introduced the WellSaid Partner Program to deliver both technical advancements and additional support for customers. The program will help companies integrate WellSaid's API into their products and go to market with co-selling support, early product access, and preferred pricing.

The WellSaid API is purpose-built for real-time applications, high-volume content pipelines, and full customization. Key capabilities include the following:

• Voices powered by WellSaid's Caruso model.
• Fine-tuned control over pitch, speed, pausing, pronunciation, and tone.
• Low-latency, streaming, and high concurrency for responsive performance.
• Support for long-form content like audiobooks, eLearning, and scripted media.
• Commercial rights included, with SOC 2, GDPR, and EU AI Act compliance.
• 1 million characters per month while users are building.

Teams use the API across a wide range of use cases, from interactive voice response systems, virtual assistants, and chatbots to audiobooks, marketing campaigns, accessibility tools, and in-game character voices.

The WellSaid Partner Program is for teams embedding AI voice into their platforms or delivering it to clients. The program offers the following:

• Preferred subscription pricing for client accounts.
• Revenue opportunities through co-marketing and co-selling.
• Early access to new API features and integrations.
• Workshops and go-to-market enablement with WellSaid's partner team.
• Dedicated support from partner managers, customer success managers, and account executives.
• Partner tiers available for startups, agencies, and technology providers.

"Developers are under pressure to move fast, stay flexible, and deliver polished experiences without blowing the budget," said Chris Johnson, chief technology and product officer of WellSaid, in a statement. "We built our API to meet those realities—high-quality voice, full control, and faster implementation, all at half the cost of other providers. With the new Partner Program, we're helping teams go further by turning that capability into a growth engine."
