Full Comparison

Criterion	Google Cloud Text-to-Speech	Vozo
Starting price	lower value Free tier, then from $4 per 1 million characters Pay-as-you-go by characters sent for synthesis, counting spaces, newlines and most SSML tags, with a free monthly allowance per voice type. Standard and WaveNet $4 per 1 million characters, free to 4 million a month. Neural2 and Polyglot $16, Chirp 3 HD $30 and Studio $160, each free to 1 million a month. Instant Custom Voice $60 with no free allowance. Gemini-TTS is billed per token instead, from $0.50 per 1 million input text tokens and $10 per 1 million output audio tokens, also with no free allowance.	Free tier; paid from $29 / month Plans are metered in AI points rather than flat minutes, so the cost follows how much dubbing, lip sync and visual translation a project uses. Each tier also caps video length and concurrent jobs.
Free trial	Free monthly allowance: 4 million characters on Standard and WaveNet voices, 1 million on Chirp 3 HD, Neural2, Polyglot and Studio voices	Free tier with 20 AI points, up to 3 projects
Output	Synthesised speech, single request, streaming or long-form, as LINEAR16, MP3, OGG_OPUS, ALAW, MULAW, PCM or M4A	Dubbed and lip-synced video, translated subtitles and translated on-screen text
API	Yes, the Cloud Text-to-Speech API with client libraries and a command-line path	Yes, on Enterprise plans
Languages	Google's own figure is 220+ voices across 40+ languages	111 source and 165 target languages
Hosting	Cloud (Google Cloud), with a global endpoint and regional endpoints	Not stated
Voice cloning	Yes, Chirp 3 Instant Custom Voice builds a personal voice model from a short high-quality recording, usable afterwards for streaming and long-form synthesis. Access is restricted to allow-listed customers and is arranged through the sales team rather than self-service. A cloning key created for en-US can also speak German, US and European Spanish, Canadian and European French and Brazilian Portuguese	VoiceREAL keeps the original speaker's tone in the dubbed track, VoiceNATIVE substitutes a native-accent voice; Voice Studio carries a library of 12,000+ voices
Real-time use	Yes, bidirectional streaming synthesis for live use, alongside ordinary single requests and a separate long-form path for large documents	Not a live pipeline: video is uploaded and rendered as a job, with one concurrent task on the free tier, 2 on Creator and 6 on Studio
Speech-to-speech and dubbing	No. This service synthesises speech from text only. Recognition is the separate Speech-to-Text service and translation the separate Translation AI service	Yes, AI dubbing of uploaded video, with lip sync from the Creator plan
Editing and controls	SSML, pace control from 0.25x to 2x, experimental pause tags and custom pronunciation in IPA or X-SAMPA phonetic encoding, device profiles that tune output for the playback hardware, and text-based prompting on the Gemini-TTS models, which take a written description of the delivery rather than markup	Yes, rewrite and redub a voiceover by editing text in Voice Studio, plus subtitle generation and embedding, on-screen text translation, and glossary and bulk upload on Studio
Consent and trust	Instant Custom Voice sits behind an allow list that is granted by the sales team, and enrolment requires the speaker to record a consent statement that Google supplies in the language being cloned, in English: "I am the owner of this voice and I consent to Google using this voice to create a synthetic voice model." The recording is part of the enrolment, so a voice cannot be cloned from found audio	Built with SOC 2 Type II controls and GDPR-aligned data handling, in the vendor's words; glossary and brand governance sit on Studio, and human review of the delivered output is an Enterprise add-on
Deployment	Cloud (SaaS), Browser-based	Cloud (SaaS), Browser-based
Support	Not stated	Email helpdesk, Chat
Onboarding	Documentation and knowledge base	Not stated
Company size	Freelancers, Small and mid-sized, Enterprise	Freelancers, Small and mid-sized, Enterprise

The trade-offs

Strengths and Limitations

Google Cloud Text-to-Speech

Strengths

One API spans cheap legacy voices at $4 per million characters and current HD voices at $30
Gemini-TTS takes a written prompt for the delivery instead of hand-written SSML markup
Free monthly character allowance on every voice type except Gemini-TTS and custom voices
Bidirectional streaming, single request and long-form synthesis from the same service
Voice cloning requires a recorded consent statement from the speaker, in their own language

Limitations

Text to speech only: recognition and translation are separate Google Cloud services
Instant Custom Voice is restricted to allow-listed customers and goes through sales
Studio voices cost $160 per million characters, forty times the Standard rate
Gemini-TTS is billed per token rather than per character, so the two price models do not compare directly
The overlapping generations of voice model take some reading before the right one is obvious

Vozo

Strengths

Very broad language coverage, 111 source and 165 target languages
Visual Translate rewrites on-screen text and keeps layout and animation
Free tier covers a first project without a card
Two dubbing modes, one keeping the original voice and one using a native accent

Limitations

API access only on Enterprise plans
Metered in AI points, so cost depends on the mix of dubbing, lip sync and visual translation
Each tier caps video length, seats and concurrent jobs
Lip sync and watermark-free export need at least the Creator plan
