How this service works
Premium natural speech with Deepgram Aura-2: 40 English voices (luna, orion, athena, zeus...) and Spanish, returned as MP3 (or base64 JSON). $0.002 plus $0.07 per 1,000 characters, minimum $0.005. Add store=true (+$0.001) to get a 7-day share link instead of the data inline.
Output
Returns either a raw MP3 audio file stream or a base64-encoded JSON object containing the audio data. If store=true is passed, returns a JSON object containing a 7-day shareable URL to the hosted audio file instead of the inline audio data.
Example use cases
Podcast-style article narration
“Read this blog post aloud using the 'orion' voice and give me an MP3 I can embed — here's the text: 'In today's fast-moving market, staying ahead requires constant adaptation and a willingness to embrace new technologies...'”
Spanish customer welcome message
“Generate a spoken welcome message in Spanish using any available voice — the text is: 'Bienvenido a nuestro servicio de atención al cliente. Estamos aquí para ayudarte en todo momento.'”
Shareable audio announcement
“Convert this announcement to speech with the 'luna' voice and store it so I can share the link with my team: 'The office will be closed on Friday, December 27th for a company holiday.'”

Endpoint
GEThttps://agents.citiviewgroup.com/v1/speak/pro?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need high-quality neural TTS with a wide selection of English voices (40 options) or Spanish, and want the output as a ready-to-use MP3 or a shareable hosted link. It is especially well-suited for agents needing to quickly produce voice content for end users, create audio announcements, or narrate text-heavy content without managing a full TTS API integration. Prefer it over generic TTS when voice variety and Deepgram Aura-2 quality are priorities, or when a 7-day shareable audio URL is needed.
Side effects
- Text exceeds 5,000 character limit — request rejected
- Invalid voice name provided — may fall back to default or return error
- Unsupported language code — only 'en' and 'es' are supported
- Invalid format value (only 'mp3' and 'json' accepted)
- Payment insufficient — x402 payment below minimum $0.005 USDC
- store link expired — 7-day share links become unavailable after expiry
