Language understanding and dialogue systems that work across every channel.

Natural language processing (NLP) is how software reads, classifies and responds to human language. We build the underlying capabilities — intent and entity recognition, extraction, dialogue state, multilingual handling — so the same conversation logic can power chat, voice, email and internal tools.

What we deliver
  • Language task design
  • Classification and extraction models
  • Dialogue management layer
  • Multilingual support
  • Text analytics outputs

Where this helps

Unstructured text nobody has time to read
Emails, survey responses, reviews and case notes pile up. The patterns and requests inside them only surface when someone happens to read the right one.
Every channel has its own logic
The website bot, the phone system and the email triage each understand customers differently, so answers and routing are inconsistent.
English works, other languages do not
The system handles English well, but customers writing in other languages get poor classification, mistranslated answers or no support at all.

What we deliver

01
Language task design
Clear definitions of the intents, categories, entities and sentiment labels your business needs, with examples and edge cases agreed with domain experts.
02
Classification and extraction models
Models or LLM pipelines that tag, route and extract structured data from text, tested against labeled samples from your own data.
03
Dialogue management layer
Channel-independent conversation logic that tracks context, fills required details, handles corrections and decides the next step.
04
Multilingual support
Language detection, translation or native-language handling, and evaluation with speakers of each supported language.
05
Text analytics outputs
Topic trends, emerging issues and sentiment summaries delivered to dashboards or as structured data for your analysts.

How it works

  1. 01

    Sample the language

    We collect representative text or transcripts and review how people actually phrase requests, including slang, typos and mixed languages.

  2. 02

    Define the schema

    Intents, entities and labels are defined with examples, then tested for how consistently people can apply them.

  3. 03

    Build and compare

    We compare prompted LLMs, smaller trained classifiers and hybrid approaches on accuracy, speed and cost.

  4. 04

    Integrate with channels

    The language layer is exposed as a service that chat, voice, email and back-office systems can call.

  5. 05

    Monitor and relabel

    Low-confidence and misclassified cases are reviewed and fed back to keep accuracy up as language shifts.

Design decisions we make with you

  • LLM or trained classifier

    Large models handle open-ended language with little setup; small trained models are faster and cheaper at high volume. Many systems route between them.

  • Shared versus channel-specific logic

    A shared language layer keeps behavior consistent. Channel experiences are built on top — see [AI Chatbots](/ai-services/ai-chatbots) and [AI Voice Agents](/ai-services/ai-voice-agents).

  • Languages and locales

    Which languages are fully supported, which are translated, and how quality is checked for each.

  • Confidence thresholds

    When the system acts on its interpretation, when it asks a clarifying question, and when it sends text to a person.

  • Sensitive content

    Detection and handling of personal data, complaints and urgent issues before text is stored or processed further.

Questions buyers ask

NLP is the capability; a chatbot is one product that uses it. The same language layer can classify emails, extract data from documents, and power both chat and voice conversations.

LLMs are now the core of most NLP work, but the engineering around them still matters — task definitions, evaluation, confidence handling, cost at volume and sometimes smaller specialized models.

Current models cover many languages well, but quality varies. We test each language you need on your own content and recommend where human review is required.

Yes. The language layer is delivered as a service your existing platforms can call, so you do not have to replace them. See AI Integration.
