Comparison Methodology

To assess the various Text-to-Speech (TTS) services and offer an unbiased comparison, we used a simple, yet effective evaluation method.

We engaged a group of people and asked them to listen to three distinct audio samples produced by each of the seven TTS providers under review. Each participant was then tasked with rating these samples on a scale from 0 (indicating poor quality) to 100 (signifying excellence).

Our rating criteria focused on three key aspects:

• Voice Clarity: This involved assessing the clarity and pronunciation of the voice in each audio sample.
• Human-Like Quality: Participants evaluated how natural and human-like each voice sounded.
• Emotional Expression: The ability of the voice to convey emotions well was also taken into account.

The aim of the survey is to offer a balanced and full analysis of Google TTS alternatives. Below are the audio clips from Google TTS and ElevenLabs for your consideration:

Rating System Overview

The following rating requests guided the survey participants in their evaluations:

• Take a moment to listen to the AI-generated text-to-speech audio clip. Is the voice clear? Does it sound like a real person? Does it express emotions well?
• Rate the clip between 0 (poor) and 100 (excellent). 0 means the voice isn't clear, sounds fake, and doesn't show much emotion. 100 means the voice is super clear, sounds just like a real person, and is full of feeling.
