Fish Audio
Free plan at 0 USD per month, no credit card required: 8,000 credits per month, up to 7 minutes of generated speech, up to 500 characters per generation, 3 public voice slots
Official pricing page (rendered, Chinese version), Free card verbatim: "$0 /month", "no credit card required", "8,000 credits per month", "up to 7 minutes of generation", "up to 500 characters per generation", "3 public voice slots", "standard generation speed". For comparison, the Plus plan (from $11 per month) has 250,000 credits, up to 200 minutes, 15,000 characters per generation, and is explicitly labelled "commercial use allowed".
The Free card's feature list includes the rows "enhanced voice cloning" and "commercial use", but the page does not make clear whether the Free plan includes them. Plus is separately labelled as commercial use allowed, so check the official terms of service and do not assume the Free plan is cleared for commercial use. Access from mainland China was not tested.
