Unlike previous iterations that prioritized simple conversion, this release emphasizes natural-language audio tags, native support for more than 70 languages, and native multi-speaker dialogue.<\/p>\n<p>This release signals a shift from \u2018black-box\u2019 audio generation toward a more granular, instruction-based workflow. The model is rolling out in preview through the Gemini API and Google AI Studio, on Vertex AI for enterprises, and via Google Vids for Workspace users.<\/p>\n<h3 class=\"wp-block-heading\"><strong>Speech Quality, Control, and Developer Workflow<\/strong><\/h3>\n<p>The standout technical achievement of Gemini 3.1 Flash TTS is its performance on industry benchmarks. The model currently reports an <strong>Artificial Analysis TTS leaderboard Elo score of 1,211<\/strong>, positioning it as Google\u2019s most natural and expressive speech model to date.<\/p>\n<p>Beyond raw quality, the update introduces a more sophisticated control layer for AI developers. Instead of relying on static configurations, developers can now use <strong>audio tags and natural-language prompting<\/strong> to <strong>steer the following:<\/strong><\/p>\n<ul class=\"wp-block-list\">\n<li><strong>Style and Tone:<\/strong> Instructing the model to shift delivery based on the context of the scene.<\/li>\n<li><strong>Pacing and Delivery:<\/strong> Directing the rhythm and emphasis of the speech to match specific narrative needs.<\/li>\n<li><strong>Accent and Dialect:<\/strong> Leveraging localized nuances within the 70+ supported languages.<\/li>\n<\/ul>\n<h3 class=\"wp-block-heading\"><strong>Native Multi-Speaker Dialogue<\/strong><\/h3>\n<p>A key differentiator for Gemini 3.1 Flash TTS is its support for <strong>native multi-speaker dialogue<\/strong>. Traditional TTS pipelines often require separate API calls for different voices, which can lead to disjointed pacing. By handling multiple speakers natively, the model maintains a more natural conversational flow, making it particularly useful for developers building podcasts, dramatic scripts, or collaborative assistant interfaces.<\/p>\n<h3 class=\"wp-block-heading\"><strong>Security and Identification: SynthID Watermarking<\/strong><\/h3>\n<p>As generative audio reaches higher levels of fidelity, the ability to identify AI-generated content becomes a technical necessity. Google has integrated <strong>SynthID watermarking<\/strong> across all audio generated by Gemini 3.1 Flash TTS.<sup><\/sup><\/p>\n<p>The implementation of SynthID is designed with two priorities:<\/p>\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Imperceptibility:<\/strong> The watermark is embedded in a way that does not degrade the listener\u2019s audio experience.<\/li>\n<li><strong>Reliable Detection:<\/strong> The watermark enables the identification of AI-generated content, assisting in the prevention of misinformation and ensuring transparency in digital ecosystems.<\/li>\n<\/ol>\n<h3 class=\"wp-block-heading\"><strong>Technical Summary<\/strong><\/h3>\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<thead>\n<tr>\n<td><strong>Feature<\/strong><\/td>\n<td><strong>Specification<\/strong><\/td>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td><strong>Model<\/strong><\/td>\n<td>Gemini 3.1 Flash TTS (Preview)<\/td>\n<\/tr>\n<tr>\n<td><strong>Elo Score<\/strong><\/td>\n<td>1,211 (Artificial Analysis TTS Leaderboard)<\/td>\n<\/tr>\n<tr>\n<td><strong>Language Support<\/strong><\/td>\n<td>70+ Languages<\/td>\n<\/tr>\n<tr>\n<td><strong>Core Features<\/strong><\/td>\n<td>Audio tags, Natural-language control, Multi-speaker dialogue<\/td>\n<\/tr>\n<tr>\n<td><strong>Safety<\/strong><\/td>\n<td>Integrated SynthID Watermarking<\/td>\n<\/tr>\n<tr>\n<td><strong>Platforms<\/strong><\/td>\n<td>Gemini API, AI Studio, Vertex AI, Google Vids<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<p>Overall, Gemini 3.1 Flash TTS represents a move toward a more \u2018authorial\u2019 approach to audio AI. By combining high benchmark performance with granular natural-language controls, Google AI team is providing the tools to build voice experiences that feel less like synthesized output and more like directed performances.<\/p>\n<hr class=\"wp-block-separator has-alpha-channel-opacity\" \/>\n<p>Check out\u00a0the<strong><a href=\"https:\/\/arxiv.org\/pdf\/2604.06425\" target=\"_blank\" rel=\"noreferrer noopener\">\u00a0<\/a><a href=\"https:\/\/blog.google\/innovation-and-ai\/models-and-research\/gemini-models\/gemini-3-1-flash-tts\/?\" target=\"_blank\" rel=\"noreferrer noopener\">Technical details<\/a>, For developers in preview available now on Gemini API and\u00a0<a href=\"http:\/\/aistudio.google.com\/generate-speech\" target=\"_blank\" rel=\"noreferrer noopener\">Google AI Studio<\/a><\/strong>, For enterprises in preview on\u00a0<a href=\"https:\/\/console.cloud.google.com\/vertex-ai\/studio\/media\/speech\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Vertex AI<\/strong><\/a>, and For Workspace users via\u00a0<a href=\"https:\/\/docs.google.com\/videos\/create?usp=blog\" target=\"_blank\" rel=\"noreferrer noopener\"><strong>Google Vids<\/strong><\/a> <strong> .\u00a0<\/strong>Also,\u00a0feel free to follow us on\u00a0<strong><a href=\"https:\/\/x.com\/intent\/follow?screen_name=marktechpost\" target=\"_blank\" rel=\"noreferrer noopener\"><mark>Twitter<\/mark><\/a><\/strong>\u00a0and don\u2019t forget to join our\u00a0<strong><a href=\"https:\/\/www.reddit.com\/r\/machinelearningnews\/\" target=\"_blank\" rel=\"noreferrer noopener\">130k+ ML SubReddit<\/a><\/strong>\u00a0and Subscribe to\u00a0<strong><a href=\"https:\/\/www.aidevsignals.com\/\" target=\"_blank\" rel=\"noreferrer noopener\">our Newsletter<\/a><\/strong>.
