Conversation intelligence

SAGARIS on how accurate AI note takers really are

Accurate to what, measured how, on whose audio? The number a vendor prints answers none of those on its own.

What the percentage measures

Accuracy is the inverse of Word Error Rate.

  • Ssubstitution
  • Ddeletion
  • Iinsertion

Accuracy is the inverse of Word Error Rate.

  • Ssubstitution
  • Ddeletion
  • Iinsertion

WER = (substitutions + deletions + insertions) / reference word count

accuracy = 1 - WER

Three mistakes in nine words: a WER of 0.33, an accuracy of 0.67.

Three different mistakes, one number

All three are weighted identically, so the percentage hides which word was lost.

Why the same tool scores 20 points apart

Published reviews of one tool have disagreed by about twenty points. The spread is the method: the audio, the reference, the mistakes counted.

Knowing who spoke is a different problem

It depends on the engine, not the vendor

Many note takers send audio to a speech engine they did not build, so two products can post different numbers for the same audio.

An empty transcript beats an invented one

In the in-person recorder, when transcription cannot run we return no transcript rather than generated text, and tests hold us to that.

Speaker turns appear only when the engine diarizes; otherwise the transcript is flat.

We do not publish a percentage from it.

We keep a Word Error Rate harness that scores transcripts against a committed set of reference texts. When a transcription provider is configured it checks real output against a floor; otherwise it skips. It is a measurement harness, not a live gate on your calls.

What buyers actually ask

Most asked first.

  • Because they transcribed different audio. Word Error Rate is a property of a recording and the engine that processed it, so room noise, accents, crosstalk and speaker count move it far more than the product does. Two published reviews of one tool can disagree by about twenty points without either being wrong.

  • It depends entirely on which words the missing 5% were. WER weights every error the same, so dropping a price, a date and a name scores identically to mishearing three filler words. Ask what was measured and on what audio before treating a percentage as quality.

  • No, and this is the most common misreading. Speaker attribution is diarization, scored separately, and it depends on whether the engine that resolved for that recording performs it. A perfectly accurate transcript can still be a flat wall of text with no idea who said what.

  • Which engine transcribes my audio, was diarization on for this recording, what audio was your number measured on, and what happens when transcription fails. The last one matters most: a tool that always returns text may simply be filling gaps rather than admitting a miss. If the tool on your shortlist is Gong, or the conversation intelligence inside Clari and Salesloft, our Gong alternatives and Clari alternatives pages compare each with SAGARIS, with the date each of their facts was read.

  • We are not going to print one here, because the argument above applies to us too. We keep a Word Error Rate harness that scores transcripts against a committed set of reference texts. When a transcription provider is configured it checks real output against a floor; otherwise it skips. It is a measurement harness, not a live gate on your calls. In the in-person recorder, when transcription cannot run we return no transcript rather than generated text, and tests hold us to that. So no: we do not publish a SAGARIS accuracy percentage.
