Multi-Voice Dialogue Mode

Two distinct AI speakers in one seamless audio file

Standard TTS reads your text in a single voice. Multi-Voice Dialogue mode does something different: it takes a scripted conversation between two or more speakers, assigns a distinct AI voice to each, and stitches all turns into one seamless broadcast-quality audio file. The result sounds like two people genuinely talking — different pitch, timbre, pacing, and personality — not one voice reading two roles. VoisLabs Dialogue mode is built for podcast producers, content creators, L&D teams, and indie authors who need multi-speaker audio without booking a recording studio or coordinating two voice actors. It works in Hindi, Tamil, Telugu, Malayalam, Kannada, Bengali, Marathi, Punjabi, Assamese, and Indian English — with 13 acoustically distinct voices to choose from.

13 Acoustically Distinct Voices

Choose from 13 Gemini voices with documented timbral contrast pairs — deep Amit with warm Priya, smooth Deepak with energetic Isha, authoritative Arjun with calm Naina. Each voice has a distinct acoustic fingerprint that listeners can track instantly.

Works in All Indian Languages

Two-voice dialogue works natively in Hindi, Tamil, Telugu, Malayalam, Kannada, Bengali, Marathi, Punjabi, Assamese, and Indian English. Write each turn in the native script — Devanagari, Tamil, Telugu, Malayalam, Bengali. No transliteration required.

Per-Speaker Tone Control

Assign a different tone preset and speed to each speaker. Host A can speak in conversational podcast style at 1.0x; Host B in a more measured explanatory tone at 0.95x. Per-turn direction makes two-voice audio feel genuinely scripted and performed.

Seamless Stitching

VoisLabs handles all audio stitching automatically. Turns flow together with natural pause timing — no manual audio editing, no gap management, no silence padding. The output is a single finished file ready for distribution.

HD WAV Download

Export in broadcast-quality WAV for mastering or MP3 for direct upload. The full 24-bit audio quality is preserved — ready for Spotify, Apple Podcasts, Audible, YouTube, or any professional distribution channel.

Podcast, Interview, Audiobook Formats

Multi-voice dialogue covers the three most common two-speaker audio formats: podcast (two hosts discussing a topic), interview (one interviewer and one guest), and audiobook (narrator + character voices). Each format benefits from clear acoustic contrast between speakers.

How It Works

1

Write your dialogue script

Script each speaker turn with a label — HOST A, HOST B, NARRATOR, CHARACTER — or use any labels that match your content format. Each turn becomes one speaker segment in the output.

2

Assign voices to speakers

Open Dialogue mode and map each speaker label to a voice from the 13-voice catalog. Choose voices with clear acoustic contrast — different pitch, resonance, and energy profiles.

3

Generate and download

VoisLabs processes all turns, applies per-speaker settings, stitches the audio in sequence, and returns a single broadcast-quality file. A 10-minute episode generates in under 30 seconds.

Frequently Asked Questions

What is Multi-Voice Dialogue mode?
Multi-Voice Dialogue mode is a VoisLabs feature that converts a conversation script into audio spoken by two or more distinct AI voices. You write or paste a script with speaker labels, assign a voice from the 13-voice catalog to each speaker, and VoisLabs generates a single stitched audio file with each speaker sounding genuinely different. The output is a finished audio file you can download and publish.
Which voices create the best contrast for a two-host podcast?
Strong two-host pairs include: Amit (Sadachbia, deep authoritative) + Priya (Sulafat, warm storyteller) — great for Hindi and English; Deepak (Charon, smooth mid-low) + Isha (Kore, clear high-energy) — works well for interview formats; Arjun (Enceladus, sharp investigative) + Naina (Vindemiatrix, calm elegant) — documentary and explainer tone. Avoid pairing two voices in the same pitch register — listeners will struggle to distinguish speakers.
Does Multi-Voice Dialogue work in Hindi and Indian languages?
Yes. Dialogue mode works natively in Hindi (Devanagari), Tamil, Telugu, Malayalam, Kannada, Bengali, Marathi, Punjabi, Assamese, and Indian English. Write each speaker turn in the native script for that language. The AI generates with correct native pronunciation and prosody — no transliteration workarounds needed.
Can I use Multi-Voice Dialogue for audiobooks with character voices?
Yes. The standard approach for AI-generated audiobooks uses a stable narrator voice for prose and scene-setting, then switches to distinct character voices for spoken dialogue. Assign the narrator role to a consistent voice (Priya or Naina work well), then assign contrasting voices to recurring characters. The output is a seamless audio file with natural voice transitions at each speaker change.
How long does it take to generate a multi-voice episode?
Generation time scales with total audio duration, not with the number of speaker turns. A 10-minute two-host episode typically generates in 15–30 seconds. A 30-minute audiobook chapter generates in under 2 minutes. All turns are processed in a single pass — you do not need to generate each speaker separately and then stitch manually.
Is the output commercial-ready for Spotify and Apple Podcasts?
Yes. VoisLabs paid plans generate broadcast-quality WAV output and include a commercial license covering podcast distribution revenue, YouTube monetization, audiobook sales, and sponsorship income. Normalize your WAV to -16 LUFS for podcast platforms and -14 LUFS for YouTube before uploading.
