DiaManT Release Notes

The following sections list every released version of DiaManT, newest first. Each section comes from the monthly OCP® Release Notes page named in its Released line.

DiaManT 10.47.1

Released: October 2026

Fixes

• Improved Handling of User-Initiated Text Conversations — Conversations that began with the user typing a message before any system prompt, combined with answer-validation rules, could end unexpectedly. These conversations now continue normally.

• This release includes security updates.

DiaManT 10.47.0

Released: September 2026

New Features

• Silent Caller Detection: DiaManT now automatically detects callers who never provide any input during a call (a built-in "SilentUser" indicator) so applications can route them directly to a transfer or hangup instead of cycling through repeated no-input prompts.

• Scheduled Application Variables: Application Variables can now be configured to activate only within a specific date/time window (e.g. a holiday notice that turns itself on and off), with no application redeploy required.

• Per-Task Agent Retry Limits: Individual agent tasks (e.g. a "Anything else?" re-ask prompt) can now override the default maximum human-agent-request and no-input-retry counts just for that interaction, allowing faster escalation when a caller explicitly asks for a human.

Improvements

• Expanded Performance Monitoring: New latency metrics covering Redis, S3, KMS, Kafka, NLU, SubDialogs, and OmAccounts calls, with breakdowns by timeout and error type, give operations teams much clearer visibility into where call time is spent.

• Clearer Diagnostic Logs: Numerous error and warning log messages across dialog processing were made more specific and consistent, speeding up production issue triage.

DiaManT 10.46.0

Released: August 2026

New Features

• Barge-In support for Agents: users can now interrupt an AI agent mid-response, consistent with standard voice interaction behavior.

• Per-Agent Speech Recognition Tuning - Applications running several voice agents can now set separate speech recognition rules and boosted vocabulary for each agent and language, instead of sharing one configuration across the whole application. This makes it easier to keep recognition accurate for agents that handle distinct vocabularies, such as product names or account terms, without affecting other agents in the same application.

Improvements

• More consistent intent confidence handling for data model inputs.

DiaManT 10.45.0

Released: August 2026

New Features

• Agent-supplied ASR/DTMF grammar override - When a DiaManT agent's action is an Ask, and it returns its own speech and/or DTMF grammar, DiaManT uses that grammar instead of the default configured agentic grammar.

Fixes

• Intent removal fix - Fixed a bug where a remove-intent effect targeting the tail position (queue="tail") removed the entire intent stack instead of only the tail intent. Now only the targeted intent is removed; other intents in the stack are unaffected.

DiaManT 10.44.0

Released: July 2026

Improvements

• Richer Agentic Session Reporting - Call detail records for agentic sessions now capture more context: the number of turns each agent handled, the goal assigned to task agents, the outcome of each tool action, the escalation queue selected at transfer, and details of any knowledge base documents retrieved. This gives supervisors and analysts a fuller picture of how each call was handled by the AI agent.

• Locale-Specific Word Boosting - Word boosting lists can now be configured per language, allowing each locale to have its own set of prioritised phrases. This improves recognition accuracy in multilingual deployments without affecting other language configurations.

• Expanded Language Support - DiaManT® now supports 18 additional locales, including Norwegian, Swedish, Japanese, Mandarin Chinese, Cantonese, Thai, Filipino, Bahasa Malay, Bahasa Indonesia, Hindi, multiple Spanish variants (Mexico, Peru, Colombia, Chile), German variants (Switzerland, Austria), English (Philippines), and English (India).

• Knowledge Base Data in Testing Studio Assertions - Knowledge base content retrieved by QnA agents during a session is now included in the DiaManT® response, enabling OCP Testing Studio® users to assert on retrieved documents as part of their automated test scenarios.

DiaManT 10.43.0

Released: May 2026

New Features

• Agentic Call Detail Records - DiaManT® now captures detailed records for each AI agent involved in a call, including the agent type, the model used, routing context, and the outcome. This gives you full visibility into how agentic applications handled each interaction, enabling richer reporting and quality analysis across AI-driven conversations.

• Per-Application and Per-Flow NLU Configuration - NLU models can now be assigned at the application level and overridden individually for each dialog flow within that application. This replaces a one-size-fits-all setup, giving application designers precise control over which language understanding models are active at each stage of a conversation.

Improvements

• Dutch (nl-NL) Locale Support - DiaManT now supports Dutch (Netherlands), expanding the range of languages available for voice application deployments.

• Preserved Voice Biometrics Identity When Search Is Disabled - When voice biometric search is turned off, the caller's enrolled identity is now retained correctly throughout the session

• Accurate Event Logging for NLU Timeouts - When the language understanding service times out or returns no result, the event is now logged with the correct classification, making call logs and diagnostic reports more accurate and easier to interpret.

DiaManT 10.42.1

Released: May 2026

• Reduced thread and resource usage in encryption.

DiaManT 10.42.0

Released: May 2026

New Features

• Concierge in OCP Flows
  DiaManT now supports a Concierge Agent that can act as the entry point of an OCP flow. The Concierge agent routes the conversation to the appropriate target or flow by returning a route tag, enabling dynamic, AI-driven call routing from the very first dialog step. For more information, go to Concierge Agent as Flow and Agentic Flows.

• Secrets Fields handling in Agents
  Fields marked as sensitive (secret) are now correctly flagged, ensuring sensitive data is handled appropriately throughout the agentic execution pipeline.

Bug Fixes

• BioUser info not fetched on NO_USER_FOUND
  Fixed an issue where Voice Biometrics user info was not being retrieved when a NO_USER_FOUND search result was returned. The fix ensures the user's info is fetched correctly when the bio user ID changes, without redundant calls.

DiaManT 10.41.0

Released: April 2026

New Features

• DTMF Intent Mapping - Added support for mapping DTMF key presses directly to intents. When a user presses a mapped key, the corresponding intent is activated. Unmapped keys follow existing DTMF behavior unchanged.

Bug Fixes

• Incorrect TTS provider - Fixed an issue where, in certain subdialog (miniApp) configurations returning responses with multiple prompt parts (for example, a normal prompt and a hold music prompt), the parent dialog could receive an incorrect TTS provider origin after the child flow completed.

Released: February 2026
