Where the site did not say, the table says so instead of guessing. | | Amazon Polly | Murmur | | --- | --- | --- | | Pricing model | Pay per use | One-time purchase | | Free tier | Upon sign-up, new customers can synthesize millions of characters for free each month for the first 12 months: 5 million characters per month for Standard voices, 1 million characters per month for Neural voices, 500 thousand characters per month for Long-Form voices, and 100 thousand characters per month for Generative voices (the first 12 months). | No free trial; 7-day refund | | Paid plans | Standard voices (pay-as-you-go): $4.00 per 1 million characters for speech or Speech Marks requests (when outside the free tier); Neural voices (pay-as-you-go): $16.00 per 1 million characters for speech or Speech Marks requested (when outside the free tier); Long-Form voices (pay-as-you-go): $100.00 per 1 million characters for speech or Speech Marks requested (when outside the free tier) | $49 one-time for one Mac, no free trial, 7-day refund | | Usage limits | Free tier allowances are per month (Standard 5 million characters; Neural 1 million; Long-Form 500 thousand; Generative 100 thousand for the first 12 months). Billing is monthly based on characters processed, and requests for both speech and Speech Marks are charged based on characters sent. AWS maintains default service limits on throttling, operations, and SSML use as described in 'Limits in Amazon Polly'. | No character, minute or credit limits | | Platforms | Web, API | macOS 15 or later on Apple Silicon | | Where speech is generated | In the vendor's cloud | Local, on your Mac | | Works offline | No | Yes, after models are downloaded | | Voice cloning | Not stated on the official site | Yes, from a short reference recording | | Languages | 100+ male and female voices in 40+ language and language variants | 600+ with the optional OmniVoice model | | Export formats | MP3, OGG (Vorbis), PCM | WAV, M4A | | Commercial use | As between you and AWS, your Polly output belongs to you; the service does not restrict storing and reusing generated speech, and there are no additional costs for generating static voice prompts that are replayed multiple times or content used in mass notification systems. You must own the rights to any third-party text you input. | Depends on the license of the model you generate with; check each model's license | 03 · Context ## What Amazon Polly does well Large voice catalog: 100+ lifelike male and female voices across 40+ languages and language variants, including Standard, Neural, Long-Form, and Generative voice engines. Pay-as-you-go pricing charged only for characters converted to speech or Speech Marks, with free caching and replay of generated audio at no additional cost. Rich controls via W3C SSML (pitch, rate, volume, whispering, Newscaster style, time-driven prosody) plus custom lexicons for pronunciation of names and acronyms. Speech Marks metadata enables synchronized visuals such as karaoke-style word highlighting and lip-synced avatar animations. 04 · Highlights ## When to stay with Amazon Polly | Decision factor | What it means | | --- | --- | | You need it on Web, API | Amazon Polly lists Web, API support. Murmur is a Mac app only, so it cannot follow you to other devices. | | You are generating speech from your own software | Amazon Polly offers programmatic access for apps and servers. Murmur has a local CLI and MCP server for automation on one Mac, which is not a hosted API for your customers. | | You want nothing to install or maintain | Amazon Polly runs its voices on the vendor's servers, so there are no model downloads and no dependence on your Mac's memory. | | Your needs fit inside the free tier | The official free tier: upon sign-up, new customers can synthesize millions of characters for free each month for the first 12 months: 5 million characters per month for Standard voices, 1 million characters per month for Neural voices, 500 thousand characters per month for Long-Form voices, and 100 thousand characters per month for Generative voices (the first 12 months). If that covers you, there is no reason to pay for anything. | 05 · Highlights ## When Murmur is the better fit | Decision factor | What it means | | --- | --- | | Your scripts are private or unreleased | Murmur generates on your Mac, so client scripts, manuscripts and drafts are not uploaded for synthesis. | | You generate a lot of audio | Amazon Polly charges through pay per use. Murmur is $49 once with no character limits, so long audiobooks and repeated retakes cost nothing extra. | | You want your own voice or a designed voice | The official Amazon Polly site does not list voice cloning. Murmur clones from a short reference recording and can design new voices from a text description. | | You produce finished audio, not just listening | Murmur is built around projects: multi-speaker scripts, per-line retakes and WAV or M4A export for editors such as Final Cut Pro, iMovie and Logic. | Explore ## Related pages Jump to guides and comparisons that pair with this topic.
