The Challenge

Where Whisper Needs Work

Measure the failure modes before choosing an intervention

01

Hallucinations Distort Outputs

Invented segments can appear around silence, noise, or weak speech. They need to be measured against the conditions in your own workload.

02

European Dialects Increase Errors

Domain shift and dialect variance can change error patterns across languages, regions, speakers, and acoustic environments.

03

Data Boundaries Need Definition

Processing location, retention, access, transfer, and training use must be documented for the architecture and data involved.

THE YPAI APPROACH

An Improvement Program, Not an API Promise

Diagnose, test, document, and control changes against the real workload

01

Managed ASR Improvement Program

YPAI helps diagnose the current system, define a representative evaluation set, test adaptation options, and establish an acceptance and regression process.

02

Language and Dialect Scope

Target languages, regional variants, vocabulary, and speaker conditions are confirmed during scoping.

03

Failure-Mode Analysis

Measure hallucinations, substitutions, omissions, formatting errors, and boundary failures against labeled examples.

04

Integration Recommendations

Document model, decoding, preprocessing, review, and output-contract changes for the existing workflow.

Capabilities

Assessment and Improvement Scope

The evaluation contract follows the languages, conditions, and downstream use case

01

Languages and Dialects

Evaluate the target languages and regional variants represented in your actual workload.

02

Streaming and Batch Evaluation

Define latency, throughput, and accuracy tests that match the current processing mode.

03

Speaker Handling

Evaluate segmentation, overlap, channel, and speaker-attribution requirements where they apply.

04

Timestamp Assessment

Measure timestamp quality against the downstream subtitle, search, or redaction use case.

05

Transcript Output Review

Include punctuation, casing, paragraphing, normalization, and terminology in the acceptance contract.

06

Integration Plan

Map model and pipeline changes to the existing API, data flow, observability, and review process.

Why YPAI

From Baseline to Regression Gate

A measured path from observed errors to controlled model changes

01

Workload Error Profile

Build a representative evaluation set and break errors down by language, condition, domain, speaker, and failure type.

02

Adaptation Plan

Compare decoding, preprocessing, vocabulary, model adaptation, and human-review options against the measured baseline.

03

Regression Gate

Define acceptance thresholds and repeatable tests before a change reaches the production workflow.

Evidence

What the Evidence Package Covers

Reproducible methodology and project-specific results

Failure-Mode Inventory

Separate hallucinations, substitutions, omissions, formatting, diarization, and timestamp failures before choosing a remedy.

Reproducible Evaluation Design

Record dataset versions, splits, references, normalization, decoding settings, metrics, and review decisions.

Project Evidence Package

Report the measured baseline, tested changes, limitations, acceptance results, and remaining risks for the scoped workload.

DATA GOVERNANCE

Defined Boundaries

Data Boundary

  • Processing locations documented
  • Access and transfer scope defined

Retention Scope

  • Retention terms agreed per project
  • Training use explicitly documented

Security and Governance

  • Controls mapped to actual architecture
  • Contract and DPA scope reviewed
Multi-layer protection active
ASR ASSESSMENT

Define the European-language evaluation scope

Share the current model, target languages, sample conditions, and the metric or failure mode that matters

Sample audio, current model, target conditions, and reference transcripts are useful inputs

FAQ

Assessment and Technical Questions

We review the current model and decoding setup, target languages, sample audio, reference transcripts, error reports, and downstream requirements.
We first measure where they occur, then compare relevant mitigations such as preprocessing, decoding changes, adaptation, confidence rules, and human review.
Only if the agreed project scope authorizes it. Processing purpose, access, retention, transfer, and any adaptation use are documented before data is handled.
The answer depends on the approved project architecture. Processing locations, storage, access, transfer, and retention are documented during scoping.
Yes. We can define a test for latency, throughput, stability, and transcript quality using the relevant codecs, packetization, network path, and concurrency.
The first engagement is an assessment and improvement plan. Any later implementation scope is proposed against the evidence, architecture, and data-boundary requirements.
