Overview Guide
Primary Speech Recognition and Word Error Rate (WER) Analysis Model (Standard Linguistic Evaluation Method):
| Linguistic Evaluation Metric | Mathematical or Algorithmic Representation | Formula Variables Defined |
|---|---|---|
| Word Error Rate (WER) | WER = (S + D + I) ÷ N × 100% | S: Count of word substitutions made in transcription. |
| Transcription Accuracy | Accuracy = (1 − WER) × 100% | D: Count of word deletions (missing spoken words). |
| Confidence Average | Confidence = Σ wi.confidence ÷ |w| | I: Count of word insertions (extra words added). |
| Spoken Speed (WPM) | WPM = Words ÷ (Durationseconds ÷ 60) | N: Total count of words in reference transcript. |
Formula Variables Defined:
- S, D, I: Counts of substitutions, deletions, and insertions between reference and hypothesis transcripts.
- N: The total number of words in the baseline reference transcript.
- wi.confidence: The individual confidence coefficient (0.0 to 1.0) returned for transcribed word i.
- WPM: Spoken speed rating, measured in Words Per Minute.
Formula Breakdown: Translating speech waveforms into text requires calculating transcription error rates. By evaluating Word Error Rates (WER) using Levenshtein distance alignments (summing substitutions, deletions, and insertions and dividing by reference word counts), the converter rates transcript accuracy. Individual word confidence factors are averaged to score translation reliability.
Step-by-Step Explanation: To convert speech to text, click the start microphone action. Grant microphone permission, speak clearly, and the browser's Web Speech API processes audio waves locally to display real-time transcribed text, calculating confidence levels instantly.
Practical Example: A spoken phrase of 10 words is transcribed. The hypothesis contains 1 substitution (e.g. "there" instead of "their") and 1 deletion. Total errors = 1+1 = 2. Word Error Rate WER = (2 ÷ 10) × 100% = 20%. The final transcription accuracy rates at exactly 80% (100% − 20%).
