Dialogue Audio

Multi-speaker dialogue audio creation with Dia TTS. Covers speaker tags, emotion control, pacing, conversation flow, and post-production. Use for: podcasts,...

Security Scan

The skill's instructions and commands match its stated purpose (Dia TTS multi‑speaker dialogue) but it directs the user to run a remote install script (curl | sh) from an external domain and recommends a CLI that will perform authentication — a proportional but risky install pattern that warrants caution.

Purpose & Capability

Name, description, and runtime instructions all align: the SKILL.md instructs use of the inference.sh CLI to run falai/dia-tts for multi-speaker dialogue, which is consistent with the stated purpose.

Instruction Scope

Instructions stay within the TTS/dialogue generation domain (how to tag speakers, control pacing/emotion, and example infsh commands). They do instruct the agent/user to install and run an external CLI and to run 'infsh login' (which will perform authentication), but they do not request unrelated system files or environment variables.

Install Mechanism

The Quick Start recommends piping a remote install script (curl -fsSL https://cli.inference.sh | sh) and downloading binaries from dist.inference.sh. That pattern (remote script executed directly) is high risk unless you fully trust and audit the installer; the SKILL.md claims checksum verification but does not embed a verifiable hash for the user to check before execution. The domains are not standard well-known package hosts in this manifest, and no offline/manual install alternative is provided other than links — overall this is the largest security concern.

Credentials

The skill declares no required environment variables or credentials, which is proportionate to its purpose. Note: the suggested 'infsh login' step will create/authenticate credentials for the inference.sh service (outside the skill's manifest) — that authentication is expected to use account tokens, so users should understand what permissions and data that account grants.

Persistence & Privilege

The skill does not request always:true, has no install spec that writes to system paths within the manifest, and is instruction-only. It does rely on an external CLI which will persist on disk after installation, but the skill itself does not request elevated or persistent platform privileges.

What to consider before installing

This skill appears to do what it says (generate multi‑speaker dialogue via Dia TTS), but be cautious about the install step. Avoid blindly running curl | sh from unfamiliar domains. If you want to use it: (1) inspect the install script before running it (download it with curl -fsSL https://cli.inference.sh -o install.sh and review), (2) verify binary SHA‑256 hashes manually against the published checksums.txt on the server before executing the binary, (3) consider installing in a sandbox/container or using a throwaway account for 'infsh login' so you limit potential exposure, and (4) check the inference.sh project's reputation, privacy policy, and what account scopes the login grants. If you cannot or will not verify the installer and checksums, treat the install step as high risk.

Create realistic multi-speaker dialogue with Dia TTS via inference.sh CLI.

Quick Start

curl -fsSL https://cli.inference.sh | sh && infsh login

# Two-speaker conversation
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Have you tried the new feature yet? [S2] Not yet, but I heard it saves a ton of time. [S1] It really does. I cut my workflow in half. [S2] Okay, I am definitely trying it today."
}'

Install note: The install script only detects your OS/architecture, downloads the matching binary from dist.inference.sh, and verifies its SHA-256 checksum. No elevated permissions or background processes. Manual install & verification available.

Speaker Tags

Dia TTS uses [S1] and [S2] to distinguish two speakers.

Tag	Role	Voice
[S1]	Speaker 1	Automatically assigned voice A
[S2]	Speaker 2	Automatically assigned voice B

Rules:

• Always start each speaker turn with the tag
• Tags must be uppercase: [S1] not [s1]
• Maximum 2 speakers per generation
• Each speaker maintains consistent voice within a session

Emotion & Expression Control

Dia TTS interprets punctuation and non-speech cues for emotional delivery.

Punctuation Effects

Punctuation	Effect	Example
.	Neutral, declarative, medium pause	"This is important."
!	Emphasis, excitement, energy	"This is amazing!"
?	Rising intonation, questioning	"Are you sure about that?"
...	Hesitation, trailing off, long pause	"I thought it would work... but it didn't."
,	Short breath pause	"First, we analyze. Then, we act."
— or --	Interruption or pivot	"I was going to say — never mind."

Non-Speech Sounds

Dia TTS supports parenthetical sound descriptions:

(laughs)      — laughter
(sighs)       — exasperation or relief
(clears throat) — attention-getting pause
(whispers)    — softer delivery
(gasps)       — surprise

Examples with Emotion

# Excited conversation
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Guess what happened today! [S2] What? Tell me! [S1] We hit ten thousand users! [S2] (gasps) No way! That is incredible! [S1] I know... I still cannot believe it."
}'

# Serious/thoughtful dialogue
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] We need to talk about the timeline. [S2] (sighs) I know. It is tight. [S1] Can we cut anything from the scope? [S2] Maybe... but it would mean dropping the analytics dashboard. [S1] That is a tough trade-off."
}'

# Teaching/explaining
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] So how does it actually work? [S2] Great question. Think of it like a pipeline. Data comes in on one end, gets processed in the middle, and comes out transformed on the other side. [S1] Like an assembly line? [S2] Exactly! Each step adds something."
}'

Pacing Control

Pause Hierarchy

Technique	Pause Length	Use For
Comma ,	~0.3 seconds	Between clauses, list items
Period .	~0.5 seconds	Between sentences
Ellipsis ...	~1.0 seconds	Dramatic pause, thinking, hesitation
New speaker tag	~0.3 seconds	Natural turn-taking gap

Speed Control

• Shorter sentences = faster perceived pace
• Longer sentences with commas = measured, thoughtful pace
• Questions followed by answers = engaging back-and-forth rhythm

# Fast-paced, energetic
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Ready? [S2] Ready. [S1] Let us go! Three features. Five minutes. [S2] Hit it! [S1] Feature one: real-time sync."
}'

# Slow, contemplative
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] I have been thinking about this for a while... and I think we need to change direction. [S2] What do you mean? [S1] The market has shifted. What worked last year... is not working now."
}'

Conversation Structure Patterns

Interview Format

infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Welcome to the show. Today we have a special guest. Tell us about yourself. [S2] Thanks for having me! I am a product designer, and I have been building tools for creators for about ten years. [S1] What got you started in design? [S2] Honestly? I was terrible at coding but loved making things look good. (laughs) So design was the natural path."
}'

Tutorial / Explainer

infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Can you walk me through the setup process? [S2] Sure. Step one, install the CLI. It takes about thirty seconds. [S1] And then? [S2] Step two, run the login command. It will open your browser for authentication. [S1] That sounds simple. [S2] It is! Step three, you are ready to run your first app."
}'

Debate / Discussion

infsh app run falai/dia-tts --input '{
  "prompt": "[S1] I think we should go with option A. It is faster to implement. [S2] But option B scales better long-term. [S1] Sure, but we need something shipping this quarter. [S2] Fair point... what if we do A now with a migration path to B? [S1] That could work. Let us prototype it."
}'

Post-Production Tips

Volume Normalization

Both speakers should be at consistent volume. If one is louder:

# Merge with balanced audio
infsh app run infsh/video-audio-merger --input '{
  "video": "talking-head.mp4",
  "audio": "dialogue.mp3",
  "audio_volume": 1.0
}'

Adding Background/Music

# Merge dialogue with background music
infsh app run infsh/media-merger --input '{
  "media": ["dialogue.mp3", "background-music.mp3"]
}'

Segmenting Long Conversations

For conversations longer than ~30 seconds, generate in segments:

# Segment 1: Introduction
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Welcome back to another episode..."
}'

# Segment 2: Main content
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] So let us dive into today s topic..."
}'

# Segment 3: Wrap-up
infsh app run falai/dia-tts --input '{
  "prompt": "[S1] Great conversation today..."
}'

# Merge all segments
infsh app run infsh/media-merger --input '{
  "media": ["segment1.mp3", "segment2.mp3", "segment3.mp3"]
}'

Script Writing Tips

Do	Don't
Write how people talk	Write how people write
Short sentences (< 15 words)	Long academic sentences
Contractions ("can't", "won't")	Formal ("cannot", "will not")
Natural fillers ("So,", "Well,")	Every sentence perfectly formed
Vary sentence length	All sentences same length
Include reactions ("Exactly!", "Hmm.")	One-sided monologues
Read it aloud before generating	Assume it sounds right

Common Mistakes

Mistake	Problem	Fix
Monologues longer than 3 sentences	Sounds like a lecture, not conversation	Break into exchanges
No emotional variation	Flat, robotic delivery	Use punctuation and non-speech cues
Missing speaker tags	Voices don't alternate	Start every turn with [S1] or [S2]
Formal written language	Sounds unnatural spoken	Use contractions, short sentences
No pauses between topics	Feels rushed	Use ... or scene breaks
All same energy level	Monotonous	Vary between high/low energy moments
