About Modulate

Modulate builds voice safety and voice-alteration technology aimed at platforms that host live spoken interactions, such as multiplayer games and social audio apps. Founded to address the gap between text moderation and the unique challenges of audio, Modulate positions itself as a specialist provider of real-time audio moderation and voice anonymization. The product suite is designed to slot into live audio stacks via SDKs and APIs, allowing companies to detect abusive speech, flag policy violations, and optionally mask or transform user voices without requiring end users to leave the session. The company emphasizes low-latency processing and developer integrations as its core value proposition.

Modulate’s feature set centers on real-time toxicity detection, voice transformation, and moderation workflows. The Voice A.I. moderation engine analyzes live audio streams for profanity, hate speech, sexual content, and contextual toxicity categories, returning labeled events or scores that can be used for auto-muting, temporary silencing, or escalation to human reviewers. The Voice Alteration/Anonymization functionality lets platforms apply voice filters or transform voice characteristics to preserve privacy or enforce identity safety; transformations are applied with millisecond-level latency for live sessions. Modulate also exposes SDKs and REST APIs for ingesting audio, receiving structured moderation signals, and managing rule sets; server-side and client-side libraries support common game engines and real-time platforms. Additionally, dashboard tools provide analytics and exportable moderation logs to feed safety workflows.

Modulate offers a tiered pricing approach with an entry-level free developer plan that gives limited monthly minutes for testing and integration. Paid plans shift to metered usage (pay-as-you-go) or volume-based monthly tiers that include higher minute allowances, SLA options, and enterprise features such as dedicated support and contract terms; exact monthly prices move with usage and can be quoted on signup or via sales for larger volume. The free tier is useful for prototyping but is limited in minutes and lacks enterprise SLAs; small studios often use the metered plan while larger platforms negotiate enterprise agreements for committed monthly minutes, custom feature support, and data residency or auditing requirements.

Typical users include multiplayer game developers integrating automatic voice-safety to reduce harassment, and community moderation teams that need scalable audio review signals. For example, a Live Ops Manager uses Modulate to automatically mute and escalate repeat offenders in voice channels, while a Social Audio Product Manager applies voice anonymization to protect minors and implement privacy features. Compared to general speech-to-text moderation vendors, Modulate is more specialized on live audio pipelines and voice transformation capabilities, making it a closer fit for games and live-voice apps than generic text/audio moderation services.

Frequently Asked Questions

How much does Modulate cost?+
Pay-as-you-go or custom enterprise contracts. Modulate offers a free developer tier for testing, then bills metered usage per audio minute or via volume plans. Exact monthly costs depend on committed minutes and enterprise add-ons like SLAs, priority support, or data residency. Contact Modulate sales for precise quotes for production volumes and negotiated discounts.
Is there a free version of Modulate?+
Yes — a Developer free tier with limited minutes. The free tier provides small monthly audio minutes and API access for prototyping, but it excludes enterprise SLAs, high-rate API quotas, and some analytics features. It’s intended for integration testing, not prolonged production use at scale.
How does Modulate compare to Hume or Google Cloud?+
Modulate focuses on live, low-latency voice moderation and anonymization. Unlike general speech-to-text vendors, Modulate targets real-time voice pipelines and offers built-in voice transformation. Competitors may provide broader transcription or multimodal analysis but lack Modulate’s specialized live voice masking and game-focused SDKs and event categories.
What is Modulate best used for?+
Live voice safety and anonymization in games and social apps. Modulate excels at automated moderation of spoken abuse, assigning categorical labels and confidence scores, and applying voice masking in real time to protect identity. It’s best when you need low-latency actions like auto-muting or privacy-preserving voice transforms during live sessions.
How do I get started with Modulate?+
Start with the Developer free tier and the SDK quickstart. Sign up at modulate.ai, retrieve your API key from the dashboard, install the Unity/Unreal/WebRTC SDK, and run the sample scene to stream audio. Validate returned moderation events and transform hooks before moving to metered or enterprise plans.
