This feature is currently limited to U.S. users. Users can also opt for generic voices with names like \"Aspen\" and \"Clover.\" Unlike OpenAI's controversial imitation of Scarlett Johansson’s voice, Meta has secured official licensing deals, reportedly paying each celebrity millions. Some celebrities have set restrictions on how their voices can be used to avoid liability.\n\nIn addition to voice updates, Meta’s AI now offers advanced image interaction features. Users can upload photos and ask questions or request changes, such as altering clothing color or background elements. While Meta demonstrated this image-editing feature with a T-shirt color change, the extent of moderation and ethical safeguards remains unclear. This move comes as Meta phases out previous celebrity chatbots and follows similar efforts by Amazon and Google.","ref_id":{"turn_index":0,"ref_type":"news","ref_index":25},"pub_date":1727285326,"attribution":"www.theverge.com"},{"type":"search_result_group","domain":"www.tomsguide.com","entries":[{"type":"search_result","url":"https://www.tomsguide.com/ai/claudes-free-voice-mode-has-landed-heres-how-to-access-it","title":"Claude's voice mode is now free for everyone - here's how to try it","snippet":"Anthropic has introduced a free voice mode for its popular AI chatbot, Claude, accessible via its iOS and Android mobile apps. This new feature allows users to have spoken conversations with Claude, who responds audibly while also displaying key points on the screen. The voice mode supports five distinct voice styles—Buttery, Airy, Mellow, Glassy, and Rounded—and is currently available in English only.\n\nUsers can activate the feature by tapping the sound wave icon in the app and selecting their preferred voice. It is particularly useful in hands-free situations, such as commuting, cooking, or multitasking. To enhance the experience, it’s recommended to use the feature in quieter settings, speak naturally, and divide complex queries into smaller parts. Users can seamlessly switch between voice and text while maintaining conversation context. While similar to voice features in ChatGPT and Gemini Live, Claude’s voice mode stands out by being free for short sessions.","ref_id":{"turn_index":0,"ref_type":"news","ref_index":30},"pub_date":1748948400,"attribution":"www.tomsguide.com"}]},{"type":"search_result","url":"https://arxiv.org/abs/2312.09911","title":"Amphion: An Open-Source Audio, Music and Speech Generation Toolkit","snippet":"","ref_id":{"turn_index":0,"ref_type":"academia","ref_index":36},"pub_date":null,"attribution":"arxiv.org"},{"type":"search_result_group","domain":"apnews.com","entries":[{"type":"search_result","url":"https://apnews.com/article/532c849ccae3ca9e9325dacfe88e0436","title":"Scarlett Johansson says a ChatGPT voice is 'eerily similar' to hers and OpenAI is halting its use","snippet":"Scarlett Johansson has raised concerns over a ChatGPT voice named \"Sky\" that she claims sounds \"eerily similar\" to her own, prompting OpenAI to pause its use. Johansson stated that OpenAI CEO Sam Altman had previously approached her to lend her voice to the AI, an offer she declined. She was shocked to hear the released voice, which others also associated with her, leading her to hire legal representation. OpenAI asserted that the voice was that of a different professional actress and not intended to mimic Johansson. However, out of respect, the company has removed the voice from its platform.\n\nOpenAI had originally unveiled ChatGPT’s voice capabilities, including five voice options like \"Sky,\" last September. The new AI model, GPT-4o, introduced recently, features enhanced interactive and emotional capabilities. Some demos have drawn criticism for perceived flirtatious behavior, highlighting concerns about gender bias in how voice assistants are designed. OpenAI insists that the voices were not modeled after celebrities and maintains privacy for the actual voice actors involved. Altman posted \"her\" on social media the day of GPT-4o's unveiling, referencing the 2013 film \"Her,\" in which Johansson voiced an AI assistant, further fueling speculation.","ref_id":{"turn_index":0,"ref_type":"news","ref_index":37},"pub_date":1716227056,"attribution":"apnews.com"}]},{"type":"search_result","url":"https://arxiv.org/abs/2504.19146","title":"Muyan-TTS: A Trainable Text-to-Speech Model Optimized for Podcast Scenarios with a $50K Budget","snippet":"","ref_id":{"turn_index":0,"ref_type":"academia","ref_index":38},"pub_date":null,"attribution":"arxiv.org"},{"type":"search_result_group","domain":"elevenlabs.io","entries":[{"type":"search_result","url":"https://elevenlabs.io/text-to-speech","title":"Free Text To Speech Online with Lifelike AI Voices - ElevenLabs","snippet":"Transform text into lifelike speech with ElevenLabs' Text to Speech.

Developed in 2022 and capable of generating a realistic voice clone using just 15 seconds of audio, the tool remains in limited use among select partners. Though integrated into services like ChatGPT's text-to-speech and used by companies like Age of Learning and HeyGen for educational and translation applications, OpenAI is opting for a cautious release strategy to encourage discussions about ethical deployment.\n\nOpenAI emphasizes that it requires explicit consent from speakers for use and embeds watermarks in generated audio to track origin. It urges retiring voice-based authentication methods for sensitive information and supports policy development to protect individuals' voices from misuse. While competitors like ElevenLabs already offer similar tools with safeguards, OpenAI's minimal audio requirement and user-friendly interface raise the stakes, prompting the company to prioritize societal resilience and public education over commercial expansion.","ref_id":{"turn_index":1,"ref_type":"news","ref_index":32},"pub_date":1711904028,"attribution":"www.theguardian.com"}]},{"type":"search_result","url":"https://arxiv.org/abs/2302.13700","title":"Imaginary Voice: Face-styled Diffusion Model for Text-to-Speech","snippet":"","ref_id":{"turn_index":1,"ref_type":"academia","ref_index":33},"pub_date":null,"attribution":"arxiv.org"}]

📝 RAW RESPONSE TEXT
Here’s a practical, developer-oriented list of free (or free-tier) AI text-to-speech tools you could use for IoT applications with realistic or celebrity-style voices. Be skeptical of “true celebrity voices” online — many free tools just offer sound-alikes and have legal/licensing limits if used in products. 🧠 1) Free/Paid Hybrid with Realistic Voices (Best for IoT APIs) ElevenLabs (Free tier + API) Why it’s relevant: Ultra-realistic TTS with emotional control, API support for integrating into apps/IoT. ElevenLabs [https://elevenlabs.io/text-to-speech] Free tier: You get a small monthly quota of free characters to test. The Interactive Story [https://www.theinteractivestory.com/interactive-video/eleven-labs-free-ai-voices] Celebrity voices: Not actual licensed celebrity voices for commercial use — but very human-sounding voices that are often used instead. Integration: REST API with SDKs, easy to embed on servers for IoT to call and stream audio. Use case: Smart speakers, voice assistants, notification systems where quality matters. Pros: Realistic, scalable, API. Cons: Free tier limited; celebrity imitation usually not legally cleared. 🕹 2) Open Source / Self-Hosted (Best for Offline / IoT) GLM-TTS (Open Source Voice Cloning) Feature: Zero-shot voice cloning (train on a short sample). GLM-TTS [https://glm-tts.com/] Benefit: You can customize voices yourself without ongoing service costs. Integration: Deploy on local hardware or cloud for IoT services. Use case: Private voice assistants, local alerts, embedded devices. Pros: Self-hosted, free. Cons: Needs compute (especially for high quality), not celebrity licensed. 🧰 3) Free Online Celebrity-Style Generators (Good for Prototyping) These are not suitable for commercial/embedded products — mostly web tools. AIVoiceLab / AI Celebrity Voice Generator – simple web TTS with celebrity-style voices. Aivoicelab [https://aivoicelab.net/en/celebrity-ai-voice-generator] VoidMagic / Media.io online tools – choose sound-alike voices quickly. VoidMagic+1 [https://voidmagic.ai/ai-celebrity-voice-generator] Limitations: Typically no API for IoT. Legal risk if you claim it’s a real celebrity voice. Use case: Rapid prototyping or demos. 🛠 4) Pure Open-Source TTS Engines (No celebrity but flexible) If celebrity voices aren’t a hard requirement but free / embedded friendly TTS is, consider: Coqui TTS / Mozilla TTS – high-quality neural TTS. Lemonfox [https://www.lemonfox.ai/blog/open-source-text-to-speech] Piper / Mimic / MaryTTS / Flite – lightweight engines for edge devices. Lemonfox [https://www.lemonfox.ai/blog/open-source-text-to-speech] Chatterbox TTS – simple MIT-licensed TTS. Chatterbox TTS [https://chatterboxtts.org/] Use case: On-device speech for smart displays, wearables, or industrial IoT. Pros: Totally free and flexible. Cons: Voices are synthetic, not celebrity imitations. ⚠️ Legal & Practical Notes “Celebrity voices” online are often just sound-alikes or unlicensed mimicry — using them in products (especially commercial/IoT) can create legal issues. For real licensed celebrity voices, most are behind paid APIs with strict terms and consent requirements. For IoT, focus on API flexibility, latency, and embedding strategy (edge vs cloud) rather than celebrity branding. 🧩 Recommendation Summary ScenarioBest ChoiceHigh quality, API + commercial IoTElevenLabs free tier → upgrade as neededOffline / edge devicesGLM-TTS or open-source engines (Coqui, Piper)Rapid prototyping celebrity vibesWeb celebrity voice generatorsNo cloud dependencySelf-hosted open-source TTS If you want code examples or deployment patterns (e.g., Node/Python API calls for IoT devices), I can provide those too.
