The Complete Guide to AI Voice Generators in 2023

If you run any kind of digital business – from blogs, to YouTube channels, podcasts, online courses or apps – you likely need professional voiceovers.

But hiring voice talent and recording studios is time-intensive and expensive.

That‘s why AI-powered voice generators are revolutionizing how audio and video content is created online.

AI voices provide the same quality as human recordings, at a fraction of the cost and effort.

For example, take the voice you just heard above from Murf AI. It would easily cost $500+ and days of effort to recreate with human voice actors.

In this monster guide, we will uncover everything you need to know about leveraging synthetic voices, including:

  • Detailed reviews of the top 7 voice platforms – features, samples, pricing
  • Use case examples – videos, podcasts, assistants
  • Tips for integrating and editing AI voices
  • The future of voice generation tech

By the end, you‘ll know exactly which tool fits your needs and budget.

Let‘s start at the beginning – understanding what AI voice generators actually do.

How Do AI Voice Generators Work?

Artificial intelligence voices leverage machine learning algorithms trained on massive datasets of human speech. By analyzing pitch, tone, accents and other vocal properties, the AI models generate brand new synthetic voices.

It‘s an incredibly complex process. Voice tech company Resemble.ai breaks it down into 5 key steps:

  1. Text analysis – break down sentence structure
  2. Text normalization – expand abbreviations
  3. Prosody prediction – determine speech pitch and volume
  4. Audio synthesis – generate raw vocal sounds
  5. Post-processing – make final tweaks to improve quality

Advancements in deep learning algorithms plus growth of training data has rapidly improved voice quality over the past decade:

AI voice quality over time

In this sample from 2016, the voice sounds very robotic and distorted. Compare it to this one from 2022 – nearly indistinguishable from a human!

Let‘s explore some stats that showcase the booming market for synthesized voices:

  • Voice synth industry projected to grow 17% per year to $5.8 billion by 2030
  • 75% of US smart speaker owners already use voice assistants daily
  • Forrester predicts 50% of households will own a voice AI device by 2025

With demand skyrocketing, tech giants are investing heavily in voice as the next computing platform.

For example, Amazon acquired voice cloning startup Modulate.ai and integrated it into their AWS Polly text-to-speech offering. Google has WaveNet, while Meta (Facebook) created Coder – an AI assistant for programmers.

Now let‘s analyze the best independent voice synth startups that have risen up over the past 5 years.

We will compare the 7 top platforms across key categories:

  • Voice quality
  • Languages & voice options
  • Features
  • Use case examples
  • Pricing
