The OCP 3.5.0 release brings a new generative voice technology, richer agentic reporting, broader language coverage, and a refreshed console experience. Below is a summary of the highlights customers can take advantage of this release.

Introducing Lexis, Omilia's Generative Voice

• Lexis Voice Model (Beta) - OCP TTS 3.0.0 introduces Lexis, Omilia's new generative text-to-speech model built to unlock the most authentic customer service experiences. Lexis delivers speech with the expressiveness, warmth, timing, and emotion of a skilled human agent, generated in real time and adapting to the context and stakes of every conversation. Launches with the en-US Rob CX Ambassador persona and SSML <speak>, <sub>,  <say-as>, <break> support. [add the website url to listen to samples: https://omilia.com/platform/voice-agents/lexis/ ]

• Expanded Lexis Voice Family & Locale Support - OCP TTS 3.1.0 adds new Spanish (Colombia & US) CX Ambassador personas, María and Andrés and extends Lexis verbalization support to en-GB, fr-CA, es-US, and es-CO, including natural handling of acronyms, currency, dates, and addresses.

• Verbalization update affecting Lexis voices only across all locales (incl. en-US): Multi-word acronyms and all-caps words are no longer spelled out letter-by-letter. Instead they are verbalized as a whole word. This will affect applications of customers with any prompt level configuration based on prior contradicting verbalization rules in place, who are migrating to Lexis voices.

• Richer SSML Support for Lexis - New <prosody>, <rate>, and <volume> tags give fine-grained control over pacing and volume, and spoken-form substitution lets you control exactly how abbreviations are read aloud. [add url to SSML tags guide updated guide]

• el-GR Voice Quality Improvements - Better pronunciation and word stress for embedded English words in Greek voices.

• Global NLU Override per Flow and miniApp - Orchestrator 1.36.1 - The NLU model driving intent recognition can now be set independently for individual flows and OCP miniApps®, letting multi-domain applications route each part of a conversation through the most appropriate model.

• Faster Agent Creation from Chat - CoPilot 1.10.0 - CoPilot can now create Concierge-in-flow nodes and fully configured QnA agents directly from a chat conversation, removing the need to build them manually in the canvas or agent builder.

• Reorderable Node Configuration & Cleaner Agent Labels - Orchestrator 1.36.1 - Configuration fields within a node panel can now be reordered by drag-and-drop, and Task Agents include a dedicated Goal field to document each agent's purpose.

Broader Language & Locale Coverage

Smarter, More Confident Conversations

• Confidence-Based Intent Clarification - miniApps 2.43.0 - A configurable confidence threshold can now be set per intent, automatically triggering clarification prompts when a caller's intent isn't recognized with enough certainty, reducing misrouted calls.

• Improved Liveness Detection at Call Start - STT 8.8.0 - deepASR® now streams a brief period of silence before speech audio begins, giving liveness detection more complete context and reducing misclassification of answering machines versus live callers.

• More Reliable Number Transcription - STT 8.8.0 - Spoken numbers are now converted to digits more consistently, reducing transcription errors for zip codes, account numbers, and menu selections.

• More Complete Speech Transcripts - STT 8.8.1 / 8.8.2 - Trailing words are now captured consistently at the end of spoken sentences, and slowly dictated zip codes are recognized more accurately.

• Liveness Detection Model Update - Liveness Detection 6.1.0 - A new RA Detection model version and normalized scoring logic improve the accuracy and consistency of liveness results, with support for zero-downtime deployments.

NLU Model Management

• Cross-Validation Results Travel with Your Models - OCP NLU 1.16.0 - K-fold cross-validation reports are now included when you export, import, or snapshot a model, so validation metrics stay attached to the model configuration as it moves between environments.

• Larger Training and Evaluation Files - OCP NLU 1.16.0 - The maximum upload size for training and evaluation files increases from 10 MB to 15 MB, so larger datasets no longer need splitting.

• Durable Evaluation Reports - OCP NLU 1.16.0 - Full evaluation reports are now stored persistently instead of expiring from temporary storage, so results stay available long after a run completes. Existing reports migrate automatically.

• Clearer Limit Messages - OCP NLU 1.16.0 - When you reach a model or application limit, the message now states whether the limit applies to your account or to the group, and what to do to resolve it.

• Recoverable Snapshot Checkouts - OCP NLU 1.16.0 - Checkouts that point to an already-deleted application can now be cleared, so you can delete or retry without raising a support request.

• Accurate Deployment Status - OCP NLU 1.16.0 - Running NLU deployments are no longer reported as stopped, giving an accurate view of what is live. Inactivity notifications are also grouped into a single message per user, with clearer wording about the 24-hour window.

• Non-Latin Characters in Context Rules - OCP NLU 1.16.0 - Matching patterns in context rules now accept non-Latin text in the interface, matching what the API already supported.

• Cleaner Model Imports - OCP NLU 1.16.0 - When a model import fails validation, such as a cross-domain mismatch, the partially created application is now removed automatically instead of being left behind.

Conversational Chat Experience

• Automatic Language Detection - Chat Connector 8.18.0 - Chat sessions now detect the visitor's browser language automatically and serve the matching conversation configuration, falling back to the default locale when no match is found.

• Secure Sensitive Data Entry - Chat Connector 8.18.0 / Webchat 2.37.0 - When a dialog requests sensitive information, the chat widget can now mask the input as it's typed while preserving the exact characters entered, keeping credentials protected throughout the conversation.

• Chat Transcript Download Mid-Conversation - Webchat 2.37.0 - Visitors can now download a full transcript at any point during an active conversation, not only after it ends.

• Guarded Handover to Live Agents - Chat Connector 8.18.0 / Webchat 2.37.0 - Chat input is now disabled with a waiting message while a conversation transfers to a live agent, and re-enables automatically once the agent joins.

Platform Operations & Console

• Refreshed OCP Console® Experience - Console 1.21.0 / Orchestrator 1.36.0 / OCP NLU 1.16.0 - The OCP Console® continues its visual and structural overhaul, with more consistent navigation, modals, and data tables across the platform, plus a broadcast option for emailing all Organization admins at once.

• Expanded Audit Coverage - OCP NLU 1.16.0 - Audit events now record the environment they originate from, and coverage extends to autocorrect application deployments and group configuration changes.

Knowledge Base & Retrieval

• Faster Responses Under Load - Pathfinder 1.9.4 - Authentication, lookups, and search operations remain consistently fast during periods of high concurrent usage, removing multi-second delays during traffic spikes.

• Reliable RAG Application Imports - Pathfinder 1.9.3 - Applications using Retrieval-Augmented Generation now respond correctly after being exported and re-imported.

Connectivity

• Cleaner Error Signaling - AGI-Connector 4.23.0 - The connector no longer sends false error alerts when a caller ends a call normally, and now surfaces specific IVR error codes for speech or prompt failures, speeding up diagnosis.

• Reliable Genesys Transfers - AGI-Connector 4.23.0 - Calls transferred from OCP® to a Genesys agent now reach the agent consistently, resolving a case where a small percentage of calls were returned to OCP as new interactions.

AI Governance
