Voice Arena
A community voice marketplace where you can discover, play, and use voices — or create your own to earn real money. Voice Arena powers the voice library for Fonada Labs' TTS playground and API.
Overview
Voice Arena is the community-driven voice marketplace at the heart of Fonada Labs. It combines voice discovery, social features, and a creator economy into a single platform. Users browse trending and top-used voices, search by language or category, and use any voice directly in the Text-to-Speech playground. Creators record voice samples in the browser (or upload on Enterprise), set free or paid pricing, and earn INR from every paid synthesis.
Discover
Browse trending voices, search by name, tag, language, or share ID. Filter by gender and category across 12 content tags.
Create
Record a 3–30 second sample in the browser (or upload on Enterprise). Set metadata, transcript, avatar, visibility, pricing, and publish to the community.
Earn
Set paid pricing on your voices (2x-5x multiplier). Earn credits on every TTS/ASR usage and redeem to your Indian bank account.
Voice Library
The in-app page is titled Voice Library at /creatives/voice-arena. Creators see tabs for Voice Library, My Voices, Earning, and Leaderboard; other users browse the library without creator tabs. When no search is active, the library displays voices in two sections (trending defaults to Daily):
Trending Voices
Top 10 voices ranked by a weighted score of plays, likes, and TTS/ASR usage. Filterable by time period: Daily, Weekly, Monthly, Yearly, or All Time.
Top 10 Most Used
Voices ranked by total usage_count — the number of times they have been used for TTS or ASR synthesis.
Search activates when you type a query, select a language, pick a gender filter, or click a tag. Results replace the trending/top sections and show matching voices ranked by usage count. Search matches against voice name, description, creator name, tags, and exact share_id. The view supports both grid and table layouts.

Becoming a Creator
The Creator role unlocks the full Voice Arena feature set. Non-creator users who click "Create Voice" see an upgrade modal prompting them to visit the Plans page. After upgrading, verified KYC is required before you can open the Create Voice dialog.
Creator Capabilities
Creating a Voice
Prerequisites: Creator plan and verified KYC. Voice creation is a two-step flow inside the Create Voice dialog (Step 1: Create Voice → Step 2: Voice Details):
Step 1: Record or upload audio
Choose a language (ASR-supported list, 23 languages including English), then use either tab:
- Browser microphone capture
- Duration: 3–30 seconds (cannot stop before 3s; auto-stop at 30s)
- Encoded as mono PCM at 44.1 kHz, 16-bit WAV
- Optional mood chips and rotating guided scripts per language
- Transcript auto-filled from the displayed script when recording stops
- Preview and re-record before continuing
- MP3, WAV, M4A, OGG, or WebM; max 25 MB
- Same duration limits: minimum 3 seconds, maximum 30 seconds
- Auto-transcription via ASR; edit or re-transcribe before continuing
- Transcript required (from ASR or typed manually)
To continue: valid audio, duration within 3–30s, and a non-empty transcript. Enterprise plan required for upload mode.
Step 2: Details & Pricing
| Field | Required | Constraints |
|---|---|---|
| Name | Yes | Max 50 characters |
| Description | No | Max 200 characters |
| Language | Yes | Set in Step 1 (read-only in Step 2) |
| Gender | Yes | Male, Female, or Neutral |
| Transcript | Yes | From recording script, ASR (upload), or manual entry; required before save |
| Age | Yes | 18–100 (used for default avatar assignment) |
| Location / Country | No | Free text (city/country pickers) |
| Avatar | No | Custom upload (JPG/PNG/WebP, max 2 MB), preset selection, or auto-assigned by age/gender |
| Visibility | Yes | Public (discoverable) or private; paid multipliers only when public |
| Pricing | Yes | Free (1x) or Paid (2x–5x multiplier) on public voices |
| Tags | No | Up to 5 from the preset list + custom tags |
Paid credit multipliers apply only to public voices. Private voices always use the 1x base rate and do not earn paid-voice revenue.
Supported Languages
The grid below lists languages used for discovery and library filtering. In the Create Voice dialog, the language picker is limited to 23 ASR-supported languages (including English) so recording scripts and upload auto-transcription work reliably. Each supported language has guided recording scripts; Enterprise upload uses ASR for the same language set.
Pricing & Credits
Every TTS synthesis consumes credits. The cost depends on text length and whether the voice is free or paid.
Credit Calculation
Base Credits
base_credits = text_length × 0.5V2 voice clone billing: 0.5 credits per character (1 credit per 2 characters). Upstream API deducts base credits; Voice Arena premium voices add an extra markup via record_voice_usage.
Free Voice (1x)
User pays base_credits only. No extra cost, no creator earnings.
Paid Voice (2x-15x)
total_credits = base_credits × multiplierextra_credits = base_credits × (multiplier - 1)The extra_credits are deducted from the user's balance and credited to the voice creator.
Creator Earnings (INR)
amount_earned = extra_credits / credits_per_rupeeWhere credits_per_rupee = 83.33 (configurable via app_config).
Example: 500-character text with a 3x voice
base_credits = 500 × 0.5 = 250
total_credits = 250 × 3 = 750 (deducted from user)
extra_credits = 250 × (3 - 1) = 500 (goes to creator)
creator_earnings = 500 × 0.50 = ₹250.00
Trending Algorithm
The trending section ranks voices by a weighted score computed from three signals:
trending_score = (plays × 2) + (likes × 5) + (usage × 10)| Signal | Weight | Source |
|---|---|---|
| Plays | ×2 | voice_plays table (time-filtered) or play_count column (all-time) |
| Likes | ×5 | voice_likes table (time-filtered) or like_count column (all-time) |
| Usage | ×10 | voice_usage_log table (time-filtered) or usage_count column (all-time) |
Time periods: Daily (24h), Weekly (7d), Monthly (30d), Yearly (365d), All Time. Time-filtered queries use the get_trending_voice_ids RPC; all-time uses get_trending_voices_alltime.
Leaderboard
The leaderboard aggregates stats per creator across all their public voices. It is visible to all users (creator tab only for authenticated creators).
score = (total_plays × 2) + (total_likes × 5) + (total_credits × 10)Columns displayed: Rank, Creator Name, Voice Count, Total Plays, Likes, Credits, Score.
Period filters: All Time, This Month (calendar month), This Week (last 7 days).
For month/week periods, data is sourced from voice_usage_log and only creators with activity in the window are shown.
