May 2026 Summaries

Coda's recent launch involved not only the challenge of training the model but also the critical task of selecting and categorizing the top voices from over 180 candidates to ensure alignment with real-world use cases. Partnering with Podonos, an audio evaluation platform, Coda conducted over eight thousand pairwise listener judgments to refine its voice catalog, classifying voices into four styles: professional, formal, casual, and energetic. These categories were crafted in response to customer feedback and are crucial for large enterprises where incorrect voice selection can have significant financial implications. The selection process involved a rigorous methodology, utilizing pairwise comparisons rather than ratings, and employed Bradley-Terry scoring to achieve a statistically robust ranking. Podonos was chosen for its ability to provide precise evaluations with a vetted panel, contrasting with platforms like Rapidata, which offer broader but less controlled assessments. The voices identified as winners in each category reflect versatility, capable of transitioning across different registers to meet varied customer needs.

Dialog Axiata PLC, in collaboration with Rime Labs Inc., has launched Sri Lanka's first enterprise-ready Sinhala text-to-speech (TTS) model, crafted specifically for the local market. This development addresses a significant gap in voice AI services by providing a high-quality, accurate Sinhala TTS solution, allowing enterprises to incorporate natural Sinhala speech into their applications. The initiative leverages Dialog's local expertise and Rime Labs' voice AI proficiency, offering advanced features such as domain-specific terminology tuning and custom brand voices. With Sinhala spoken by approximately 16 million people, the model provides a new linguistic resource for developers, who previously had to settle for English or lower-quality Sinhala synthesis. The model supports both on-premise and cloud deployment, catering to industries with stringent data privacy needs. Dialog's history of AI innovation in Sri Lanka, including multilingual platforms and advisory tools, positions this model as a pivotal step in expanding digital accessibility and fostering the growth of Sinhala voice AI technologies across various sectors.

Coda, the latest text-to-speech model developed by Rime, aims to revolutionize voice applications by addressing persistent challenges in the field, such as the tradeoff between quality and reliability and the need for conversationally engaging output. Built specifically for high-stakes conversations, Coda utilizes two jointly-trained autoregressive decoders for semantic and acoustic understanding, capturing the nuances of human speech including pitch, breath, and rhythm. Unlike its predecessors, Coda demonstrates significant improvements, particularly in multilingual settings, outperforming both Rime's previous flagship, Arcana, and competitors. Engineered with a proprietary dataset and a custom dual-decoder inference stack, Coda operates on TIGERSTRIPE, Rime's orchestration layer, offering robust performance and scalability. Currently live in public beta, Coda invites developers to explore its capabilities, emphasizing its role in enhancing the empathy and relatability of voice interactions in real-time human conversations.

A well-chosen enterprise text-to-speech (TTS) system can significantly enhance customer service interactions by providing natural and emotionally nuanced conversations that meet compliance and security standards such as SOC 2, HIPAA, PCI, and GDPR. Key considerations for selecting a TTS system include voice realism, latency, deployment flexibility, customization, and integration capabilities, ensuring that the system aligns with the organization’s specific requirements. Systems like Rime offer low-latency performance, compliance across multiple regulatory frameworks, and deployment options ranging from public cloud APIs to on-premises solutions, making them suitable for various industries, including healthcare, finance, and government. Effective TTS solutions should integrate seamlessly with existing CRM and workflow tools, support multilingual capabilities, and maintain redundancy for reliability under peak loads. Cost considerations extend beyond initial pricing to include compliance, integration, and maintenance overheads, with a focus on achieving a reliable, scalable, and secure customer experience.
