Claude's voice mode was released in 2025 and, as TechCrunch reported, was originally "powered by the Haiku model," which "provided quick responses, but wasn't well suited for complex work" (E2). The Verge similarly noted that "until now, voice mode has only been available on Claude Haiku, Anthropic's faster but less powerful model" (E10). According to TechCrunch, Anthropic said on Thursday that "users can choose between Opus, Sonnet, and Haiku models" (E1)—meaning the feature has gone from a single, faster model to a three-model lineup.
The Verge reported that Anthropic's own blog post explained users were "immediately" using voice mode for more than simple Q&A, working "through real business problems," which Haiku "was not really designed for" — the model "kept conversations quick, but not always deep" (E11). By contrast, Anthropic described Sonnet and Opus as deeper models "designed for hard problem-solving" that "can deliver more complex responses and analysis, and then take action on your behalf" (E12). The stated rationale, per The Verge, is a trade-off between speed (Haiku) and depth (Sonnet/Opus).
TechCrunch reported that "with the new update, voice mode picks the last model people used in the text chat and uses its fastest version by default" (E3). The Verge added that this selection is not fixed for the session: "users can shift back and forth between text and voice mode mid-conversation, as well as change models. So if a quick chat with Haiku sparks an idea, you can explore it further by seamlessly switching to Opus" (E13).
According to TechCrunch, "Claude's voice mode can tap into other apps like Gmail, Google Calendar, Slack, Canva, and Notion," allowing users to "ask it to update a meeting slot, draft an email, or create a document in Notion" (E5). The Verge similarly noted the update is "extending its reach into apps like Gmail, Slack, and Canva" (E10). TechCrunch framed this as a point of contrast with a rival: "this is a big difference from OpenAI's voice mode, which updated its conversational style but still isn't able to use different tools to get work done" (E6).
Here the two outlets describe two different stages of the rollout. TechCrunch reported that "earlier this year, Anthropic added multilingual support to Claude's voice mode in beta," requiring users to "manually specify the language," with support at that point covering English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese (Brazilian), and Spanish (Latin America/Spain) (E7). The Verge, describing the same release announced Thursday, said Anthropic is "expanding voice mode to several new languages," noting that "until now, languages other than English were only available in beta, but now voice mode is available in French, German, Spanish, Hindi, Indonesian, Italian, Japanese, Korean, and Portuguese" (E14) — i.e., nine non-English languages moving out of beta.
| Source | Status described | Languages listed |
|---|---|---|
| TechCrunch (E7) | Beta, manual selection required | English, French, German, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese (Brazilian), Spanish (Latin America/Spain) — 10 total |
| The Verge (E14) | Moving from beta to general availability | French, German, Spanish, Hindi, Indonesian, Italian, Japanese, Korean, Portuguese — 9 total |
TechCrunch reported that "the new voice mode is available to all users in beta across platforms," but with a tiered restriction: "free users will be restricted to using the Haiku model with only one connected app" (E8).
| Tier | Model access | Connected apps |
|---|---|---|
| Free users | Haiku only | 1 app |
| Paid users (implied) | Opus, Sonnet, Haiku (E1) | Multiple apps (Gmail, Google Calendar, Slack, Canva, Notion per E5) |
According to TechCrunch, no. "Anthropic didn't make any changes to the voice model with this release, and it hasn't detailed what kind of voice stack it uses." The outlet noted this means "unlike OpenAI's release, users might not find any conversational improvements such as better interruption handling" (E9). The update, in other words, changes which models power the responses and which apps voice mode can reach, but not the speech engine itself.
TechCrunch reported that Anthropic said "the new voice mode can help users with longer conversations, including providing feedback on their communication style, talking through a pitch to a client, and brainstorming product market research" (E4). This description aligns with The Verge's account of Sonnet and Opus being positioned for "hard problem-solving" rather than quick exchanges (E12).
Taken together, the two accounts describe an update that widens capability along three separate axes at once: model choice (Haiku alone → Haiku, Sonnet, Opus, per E1/E10), app reach (voice-only → five connected apps including Gmail, Google Calendar, Slack, Canva and Notion, per E5), and language coverage (English-only at launch → nine non-English languages reaching general availability, per E14). Yet TechCrunch's reporting shows the update is bounded in one respect: the voice model and its underlying stack were left untouched (E9), and free-tier access remains capped at Haiku and a single app (E8) even as paid access spans the full model lineup. The discrepancy between TechCrunch's beta-language list (10 languages, manual selection) and The Verge's general-availability list (9 languages) also suggests the multilingual feature moved through more than one rollout stage before this week's announcement.
According to TechNews and China Times reports, Meta is preparing a $12 billion bond sale through a BlackRock-backed SPV for a Texas data center, with investors demanding yields above 7%—about 0.4 percentage points higher than Meta's October 2025 Hyperion deal. MoneyDJ reports Alphabet's Q2 free cash flow turned negative for the first time as capex surged, underscoring investor unease over AI spending.
According to a CNA report (carried also by CTS), Taiwan's King Slide (川湖) says its Houston plant will start mass production in the third quarter, while Chenbro (勤誠) has already opened a US NCT site in March and signed a Dallas plant deal in May, as both AI supply-chain suppliers post sharp first-half revenue gains.
According to CNA (中央社) and Technews (科技新報), new U.S. Section 301 tariffs took effect July 24, setting Taiwan's rate at 10% versus 12.5% for China and Japan. Taiwan Institute of Economic Research (台經院) president Chang Chien-yi called the outcome favorable, while analyst Liu Pei-chen said impact on Taiwan's chip sector is limited, with advanced nodes largely shielded and mature nodes more exposed to a pending overcapacity probe.
