Core Strengths

One Interface, Eight Cloud Voice Brands

Soniva integrates Alibaba Cloud Bailian, Doubao Speech (Volcano Engine), MiniMax, Tencent Cloud, Baidu Cloud, Microsoft Azure, ElevenLabs, and Cartesia — eight cloud AI voice brands.

Each of these eight has completely different signature/auth protocols, billing bases, and per-request length limits. Soniva flattens that into three steps: "choose brand → choose model → choose voice." You don't need to open accounts on eight separate platforms.

Two more free voice sources on top of that:

System built-in voice: directly uses the reading engine on your device (Apple voices on Mac/iPhone, Microsoft voices on Windows, Google voices on Android/Chrome). Free forever, unlimited, and requires neither a subscription nor login.
Bring Your Own Key (BYOK): if you already have a developer account at an upstream platform, enter it and requests go directly through your own account — Soniva deducts zero credits.

One Credit Pool, Fully Transparent Pricing

No matter which brand you use, deductions pull from the same credit balance — no more "Brand A's quota is used up while Brand B's sits idle."

Rates follow a single public formula: credits / 1,000 chars = official upstream USD price × 1.15. Each tier's upstream price, source link, and verification date are all listed in the full credit rate table, so you can cross-check them on each vendor's official site yourself.

Auto-Segmented Long Text

Text over the per-request length limit is automatically split into segments and read in sequence — no manual splitting needed.

Pre-Render Translation (Including Image Translation)

You can translate text into a target language before reading it aloud, or paste an image for it to recognize and translate. Translation runs on a separate character quota and consumes no credits — the free tier has 5,000 chars/day. You can switch between DeepSeek / Alibaba Cloud Bailian / Volcano Ark / Zhipu GLM, and all four support image input. See the translation guide.

Session Sync & Multiple Accounts

After logging in, past sessions auto-sync to the cloud and are visible across devices. You can switch between multiple accounts, with each account's data isolated. Sync doesn't require a subscription — just login.

Start Your First Reading in 3 Steps

Paste or type any text in the chat input box.
Press Enter (or click the send button) to start reading.
Use the bottom control bar to adjust the speech rate (0.75x / 1x / 1.25x / 1.5x / 2x), or pause and switch voices.

The first time you use it, it defaults to system built-in voice — no login, no cost. To hear cloud AI voices, use free previews — six brands each offer one representative voice, playable for free 5 times per brand per day.
