Overview

Vowel-Consonant Processor analyzes English text or transforms selected vowels and consonants. Choose analysis, replacement, removal, or duplication to receive JSON results with letter counts, zero-based positions, per-word statistics, transformed text, and change steps.

When to use

  • Count vowels and consonants in an English sentence without changing the original text.
  • Replace or remove selected vowels, consonants, or both using a chosen marker or target.
  • Inspect letter positions and transformation steps for a clear text-processing audit trail.

How it works

  1. 1Paste English text into the Text Input field.
  2. 2Choose an operation: Analyze, Replace, Remove, or Duplicate.
  3. 3Select vowels, consonants, or both as the target.
  4. 4For replacement or duplication, set the replacement text or a duplicate count from 2 to 5; optionally treat Y as a vowel.

Use cases

  • Analyze word and sentence composition by counting vowels, consonants, and their positions.
  • Create masked text by replacing vowels, consonants, or both with a chosen marker.
  • Test letter-based text transformations with repeatable settings and inspect each recorded change.

Examples

1. Analyze a pangram

Language learner

Background

A language learner wants to inspect the letter composition of a short English sentence while keeping the original wording unchanged.

Problem

Manually counting vowels, consonants, and character positions is slow and can lead to indexing errors.

How to use

Enter `Sphinx of black quartz`, select Analyze, and target Vowels and consonants.

Treat Y as a vowel: off

Outcome

The JSON result reports letter counts, zero-based positions, per-word counts, and the unchanged result text.

2. Replace vowels with a marker

Text-processing tester

Background

A developer is testing a simple masking rule on a short phrase and needs to verify which characters changed.

Problem

The developer needs to replace vowels only and review an exact record of every replacement.

How to use

Enter `Read code`, select Replace, target Vowels, and set the replacement to `@`.

FAQ

What type of text does the tool process?

It processes English text and identifies English vowels and consonants.

What operations are available?

You can analyze, replace, remove, or duplicate selected vowels and consonants.

Can I process only vowels or only consonants?

Yes. Set the target to Vowels, Consonants, or Vowels and consonants.

Does the tool count the letter Y as a vowel?

By default, Y is not treated as a vowel. Enable Treat Y as a vowel to change this behavior.

What does the JSON result include?

Results can include counts, zero-based positions, per-word statistics, transformed text, and detailed change steps.
