Release notes

February 2026

Kinyarwanda and Oshiwambo language support

Kinyarwanda and Oshiwambo are now supported for speech-to-text and text-to-speech. Both languages are powered by Proto’s own NLP model, purpose-built for intent classification in low-resource languages where general-purpose AI models do not perform reliably.

External voice API

Speech-to-text and text-to-speech for Kinyarwanda and Oshiwambo are now available as an external API, allowing third-party integrations to convert voice and audio directly through Proto. Usage is tracked per teamspace for billing purposes. The text-to-speech endpoint returns audio in Opus format, reducing response size and improving playback performance. A gender option is also supported for both languages.

Voice support on LINE

Voice messages – both speech-to-text and text-to-speech – are now supported on the LINE channel.

Analytics colour themes

A colour theme selector has been added to the Analytics module, allowing you to customise how data is displayed across charts and graphs.

Webchat voice button

Webchat now includes an optional large voice button, making it easier for end users to notice and use voice messaging. The button style can be switched between a prominent standalone button and a compact inline option in the Webchat settings.

Other improvements

Billing now supports pricing plans with no monthly interaction quota, enabling API voice-only setups.
Date-time displays across the platform now follow a consistent 24-hour format, and the date-time picker now supports second-level precision.
Hyperlink support has been added to all text fields in the Collect Feedback action.
Livechat, Ticket, and People modules now support filtering by empty or unset fields. You can select “None” in filter dropdowns for tags, custom fields, assigned agent, team, CSAT score, country, and more.
Platform copy cleaned up across Analytics labels, filter terms, and interaction naming.
