Google Cloud Text-to-Speech vs Voicemaker

Google Cloud Text-to-Speech is an API that converts text or SSML into audio data for applications. It offers more than 380 voices across more than 75 languages and variants, with REST or gRPC integration and output formats including MP3, LINEAR16, OGG_OPUS, MULAW, and ALAW. Gemini-TTS supports single- or multispeaker speech guided by natural-language prompts for style, accent, pace, tone, and emotional expression. Chirp 3 instant custom voice can create a personalized voice model from as little as 10 seconds of audio and is available in more than 30 locales. Streaming synthesis supports real-time conversations, while long-audio synthesis accepts up to 1 million bytes of input. Speech controls include pitch, speaking rate, and volume gain. Billing counts input characters, including spaces, newlines, and SSML tags except the mark tag, and billing must be enabled. Standard and WaveNet voices cost US$4 per 1 million characters, with 0 to 4 million characters free. Other voice models have different rates and free-use limits. New customers can receive $300 in Google Cloud credits.

Voicemaker turns typed or pasted text into audio, with controls for voice speed, pitch, and volume. Its listed tools also include speech-to-speech voice conversion and speech-to-text. The voice library lists 500 voices, and the service supports up to 140 languages on paid plans; the Free plan lists 120. Output formats include MP3, OGG, WAV, OPUS, AAC, and telephony audio. Voicemaker is available on the web and through a pay-as-you-go REST API for integrating text-to-speech, speech-to-speech, and speech-to-text into apps and workflows.

The Free plan costs nothing and allows limited generations, up to 250 characters per conversion, and personal use. Starter costs $5 a month and includes 200,000 monthly credits, a 3,000-character limit, and 140 languages.
